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°.

Plot schematically the tensile stress versus strain curves for a typical thermoplastic material at a temperature below its glass transition temperature (tg and at a temperature above its tg, respectively. do the same for a typical thermosetting material. list in a table any differences or similarities between the two materials at t> tg and t < tg, respectively, and relate them to the structures of the two types of polymers
