During a classroom demonstration, the instructor clumsily fails in an attempt to push a 2.001 cm diameter brass sphere through a 1.999 cm opening in a steel ring. the instructor then heats the steel ring until the sphere “just” slips through the opening. if the initial temperature of the ring is 20.0 oc, calculate the minimum temperature of the ring at which the sphere slips through the hole. note that the coefficient of linear expansion of steel is 12x10-6 oc-1

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
