A three-point bending test is performed on a glass specimen having a rectangular cross section of height d = 5 mm (0.2 in) and width b = 10 mm (0.4 in); the distance between support points is 45 mm (1.75 in) (a) Compute the flexural strength if the load at fracture is 290 N (65 lbf). (b) The point of maximum deflection, Ay, occurs at the center of the specimen and is described by FL3 Ay = 48E1 where E is the modulus of elasticity of 69 GPa and I is the cross-sectional moment of inertia. Compute Ay at a load of 266 N (60 lbf).

A uniform plane wave has an electric field vector that is given by E(x, y, z, t) = (12x - 50y) cos (10^9 t - kz) [V/m] This plane wave is propagating in polypropylene (epsilon_r = 2.0), which may be assumed lossless and non-magnetic. Find the following (and make sure that you include units): (a) k; (b) lambda; (c) E(x, y, z); (d) H(x, y, z); (e) H(x, y, z, t)

One of the reasons that the launch had so many bugs was that the engineering team missed a critical system dependency that they had on another Amazon team. In the scramble to fix this, several high priority bugs did not get addressed before launch and this was not communicated to the product team so they could adjust the launch timeline. You are about to meet with the engineering team lead to talk through what could have been done better. How do you approach the meeting

The cooling load of a building in Yorktown, NY (latitude of 41.29o N) reaches it maximum at about 3:00PM solar time. To make up for the high demand of electricity for the air-conditioning unit the homeowner uses a photovoltaic system. The maximum electric power of a photovoltaic panel is when the solar beams are perpendicular to their surface. Determine the orientation (tilt and azimuth angle) for maximum eclectic power at 3:00PM solar time on August 5th

Using the Breguet range and endurance equation, estimate the amount of kerosene fuel needed for an aircraft weighing 10 metric tons (this is the dry weight that includes passengers and cargo) to fly from Boston to Los Angeles, assuming a distance of 5,000 [km], flying at 300 [m/s].Assume a lift-to-drag ratio of 15 - this is the ratio of lift force over drag force during the cruise, the overall efficiency of 0.3, and about half of the standard air density at an altitude of approximately 6,000 [m]. You can neglect the climb and descent phases of the flight. The energy density of kerosene is 775.0-840.0 g/L.
