The wheel on a bench grinder has a diameter of 0.3048 m and a mass of 2.4 kg. It is spinning at 26.2 rad/s when the grinder is turned off. It takes 150 seconds for the wheel's angular velocity to drop to 13.1 rad/s.
a.) Calculate the angular acceleration of the wheel.
b.) Calculate the net torque on the wheel.
A solid uniform 3.25 kg cylinder, 65.0 cm in diameter and 12.4 cm long is connected to a 1.5kg weight over two massless frictionless pulleys. How fast is the cylinder turning at this instant
A guitar string is being restrung with a string having a diameter of 1.4 mm and a length of 0.82 m when no tension is applied. If the string has a Young's modulus of 1.4 x 10^11 N/m^2 and is tightened by wrapping it three times around a peg with a 2...
