A pulley-block system is used for testing in a UHart mechanics lab. The pulley has an outer radius of R = 0.75 m, an inner radius of 0.44 m, a mass-moment of inertia of IG = 7.5 kg*m2 , and is constrained to rotate about its mass center G. The inner radius has a cord wrapped around it that is used to pull the block, which has a mass of 5.8 kg. The coefficient of friction µ between the block and the surface is 0.37. A second cord wound around the outer radius of the pulley is pulled down with a constant force F of 22 N which starts the system from rest. There is no slip between the cords and the pulley. (a)(15 points) Draw the FBD and the MAD for the system, showing all forces and resulting motions, (b) (20 points) Determine the angular velocity ω of the pulley after 5 seconds.

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
