Asolid cylinder of mass 10 kg is pivoted about a frictionless axis thought the center o. a rope wrapped around the outer radius r1 = 1.0m, exerts a force f1 = 5.0 n to the right. a second rope wrapped around another section of radius r2 = 0.50 m exerts a force f2 = 6.0 n downward. what is the angular acceleration of the disk?

Amachinist needs to remove a tight fitting pin of material a from a hole in a block made of material b. the machinist heats both the pin and the block to the same high temperature and removes the pin easily. what statement relates the coefficient of thermal expansion of material a to that of material b? a) the situation is not possible, heating block b will shrink the hole in the material as the material expands with increasing temperatureb) material b has the same coefficient of expansion as does material ac) material b has a negative coefficient of expansion and a has a positive coefficient of expansiond) material a has a greater coefficient of expansion than does material be) material b has a greate
