Question details

Jwboor Q1) A 0.5 m externally contracting brake drum has heat-dissipating surfaces whose mass i 20-Ag The brake torque capacity of 300 N.m.The brake is used to brink a rotating inertia to a complete stop. Determine the temperatere rise if the inertia has an initial speed of 1800 rpm and is brought to rest in 8 seconds using the fell torqr capacity of the brake. The steel specific heat e,- 500 jkg.e. |1S Mark)
