II. Screw: KE to GPE.

III. Wheel and axle: GPE to KE.

IV. Lever: GPE to KE.

V. Wedge: GPE to KE.

VI. Pulley: GPE to KE.

Explanation:

A simple machine can be defined as a type of machine with no moving parts but can be used to perform work.

Basically, a simple machine allows for the transformation of energy into work. The six simple machines are;

I. Inclined plane: gravitational potential energy to mechanical energy (kinetic energy). It is set at an angle and then used to lift an object.

II. Screw: kinetic energy to potential energy. It is held in position and then used to tighten two or more objects together.

III. Wheel and axle: gravitational potential energy to mechanical energy (kinetic energy). It comprises of two circular objects which aids in the motion of an object such as a car.

IV. Lever: gravitational potential energy to mechanical energy (kinetic energy). It comprises of a pivoted bar at a fixed point (fulcrum) that allows it to be used for lifting heavy objects.

V. Wedge: gravitational potential energy to mechanical energy (kinetic energy). It can be used to split objects into halves.

VI. Pulley: gravitational potential energy to mechanical energy (kinetic energy). It is made up of a wheel and rope which allows force to be multiplied such as in a drawing well.

Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;

a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.

b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.

D. Electric meter

Explanation:

An electric meter is a metering device that is used for the measurement of the electric power consumption of an electrical powered tools, a living space or a building

Electric meter readings are used by electric utility company to sell electric power to consumers at a given rate such that it allows the electric utility company to receive payment for the total power supplied, and for the consumer to regulate the amount of power consumed

The electric meters are usually calibrated in kilowatt hour (kWh) and prepaid meter displays the amount of units of power bought, while post paid meters are usually read once each billing period which is usually one month.

Now, though he understands what the final product will look like, the camera still required further development and modification. This is simply an engineering design process because it involves finding a need and trying to solve it since he already understands what the final product will be.

Answer:

To do this, engineers often use a technique called "brainstorming." Brainstorming is a team creativity activity that helps you generate a large number of potential solutions to a problem or challenge.

Engineers use the engineering design process when brainstorming solutions to real-life problems; they develop these solutions by testing and redesigning prototypes that work within given constraints.

Engineers will often use reverse-engineering to solve problems. For example, by taking things apart to determine an issue, finding a solution and then putting the object back together again. Engineers know how things work, and so they constantly analyse things and discover how they work.

Answer:

S2 = 60 RPM.

Explanation:

Given the following data;

Gear ratio = 40/24 (T2 = 40 and T1 = 24).

Speed of driving gear = 100 RPM

To find the speed of the driven gear;

Mathematically, gear ratio in terms of speed (RPM) is given by this formula;

[tex] S_{1} * T_{1} = S_{2} * T_{2} [/tex]

Where;

Substituting into the equation, we have;

[tex] 100 * 24 = S_{2} * 40[/tex]

[tex] 2400 = 40S_{2} [/tex]

[tex] S2 = \frac {2400}{40} [/tex]

S2 = 60 RPM.

Therefore, the speed of the driven gear is 60 revolutions per minute.

Answer:

1) The speed of the roller coaster at the bottom is approximately 15.65 m/s

2) The acceleration of the roller coaster at the bottom is 6·g's

3) The high acceleration is 6 times the force of the weight of the  passengers

The high acceleration can cause gravity induced loss of consciousness

4) Please find attached a force diagram of the forces at the bottom of the roller coaster created with Microsoft Visio

5) For the acceleration at the bottom to be 2·g's the radius of the rollercoaster at the bottom should be 25 meters

5) The radius at the bottom of roller coasters are increased to reduce the normal force felt by the passengers as they pass the bottom of a circular roller coaster

Explanation:

1) The given parameters are;

The radius of the roller coaster, r = 5.0 m

The speed of the roller coaster = Minimum = 0 m/s

The shape of the roller coaster's path = Circular loop

Therefore, the maximum height of the roller coaster, h = The diameter of the of a circular path of the roller coaster, d = 2 × r = 2 × 5.0 m = 10.0 m

∴ h = 10.0 m

The minimum speed is f=given by the following equation;

[tex]F_N = \dfrac{m \cdot v^2}{R} - m \cdot g = 0 \ (At \ the \ top \ of \ the \ roller \ coaster's \ path)[/tex]

Therefore, we have;

[tex]\dfrac{m \cdot v^2}{R} = m \cdot g[/tex]

From which we have;

v = √(R × g)

Where;

R = The radius of the path of the roller coaster = 5.0 m

g = The acceleration due to gravity = 9.8 m/s² = constant

By plugging in the values of the variable, 'R', and the constant, 'g', we get;

v = √(5.0 m × 9.8 m/s²) = 7 m/s

The minimum speed of the roller coaster, v = 7 m/s

The speed of the roller coaster at the bottom is given by the conservation of energy formula as follows;

The energy at the top of the roller coaster = The energy at the bottom of the roller coaster

∴ The total mechanical energy of the roller coaster, M.E., is constant and at the top, [tex]M.E._{top}[/tex], is given as follows;

[tex]M.E._{top}[/tex] = 1/2·m·v₁² + m·g·h₁

At the bottom, the total mechanical energy is given as follows;

[tex]M.E._{bottom}[/tex] = 1/2·m·v₂² + m·g·h₂

Where;

v₁ = The velocity of the roller coaster at the top = 7 m/s

h₁ = The height of the roller coaster at the top = 10 m

v₂ = The speed of the roller coaster at the bottom

h₂ = The height of the roller coaster at the bottom = 0 m

g = The acceleration due to gravity = 9.8 m/s² = Constant

By plugging in the values, we get;

M.E. = [tex]M.E._{top}[/tex] = [tex]M.E._{bottom}[/tex]

∴ 1/2·m·v₁² + m·g·h₁ = 1/2·m·v₂² + m·g·h₂

1/2 × (7 m/s)² + 9.8 m/s² × 10.0 m = 1/2 × v₂² + 9.8 m/s² × 0 m

122.5 m²/s² =  1/2 × v₂²

∴ v₂² = 2 × 122.5 m²/s² = 245 m²/s²

v₂ = √(245 m²/s²) = 7·√5 m/s ≈ 15.65 m/s

The speed of the roller coaster at the bottom, v₂ ≈ 15.65 m/s

2) The normal force on the car at the bottom of the roller coaster is given as follows;

[tex]F_N = \dfrac{m \cdot v_2^2}{R} + m \cdot g = m \times \left(\dfrac{ v_2^2}{R} + g \right )[/tex]

Force, F = Mass, m × Acceleration, a

∴ F = m×a

Therefore, the acceleration at the bottom, 'a' by comparison of the general equation for force, 'F', and the normal force, [tex]F_N[/tex], is given as follows;

[tex]a = \left(\dfrac{ v_2^2}{R} + g \right )[/tex]

Plugging in the values for 'v₂²', 'R', ang 'g', gives;

[tex]a = \left(\dfrac{ v_2^2}{R} + g \right ) = \left(\dfrac{ 245}{5} + 9.8 \right ) = \left(49+ 9.8 \right ) = (5 + 1) \times 9.8 = 6 \times 9.8 = 6 \times g[/tex]

a = 6·g = 58.8 m/s²

3) The high acceleration will lead to a very high normal force (equal to 6 times each of their weight) experienced by the passengers with a force

The high acceleration is dangerous and can lead to gravity induced loss of consciousness since it is more than 3·g's

4) Please find attached the force diagram at the bottom of the roller coaster created with Microsoft Visio

5) For the acceleration at the bottom to be 2·g's, we have;

[tex]a = \left(\dfrac{ v_2^2}{R} + g \right )[/tex]

At a = 2·g, we have;

[tex]2 \cdot g = \left(\dfrac{ v_2^2}{R} + g \right )[/tex]

[tex]\therefore 2 \cdot g - g = g = \dfrac{ v_2^2}{R}[/tex]

[tex]R = \dfrac{ v_2^2}{g} = \dfrac{245}{9.8} = 25[/tex]

R = 25 m

The radius at the bottom of the roller coaster should be 25 meters so that only 2·g's is felt

5) The shape of the roller coaster has an increases the radius at the bottom so as to reduce the acceleration of the car
