Compare thermoplastic and thermosetting polymers on the basis of mechanical characteristics upon heating

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

What is a monomer? how do they form a ploymer from the view point of chemical bonding?
