Ametal hoop with a mass of 2 kg and a radius of 0.5 m is released from rest on the incline. if the coefficients of static and kinetic friction are hs = 0.20 and 4x = 0.15, (a) determine the angular acceleration of the hoop, (b) determine the acceleration of point g, (c) determine the friction between the hoop and the incline, repeat parts (a), (b), (c), (d), (e) if the inclined angle is 30°.

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.
