Homework Statement
A pendulum has a mass of 7.5 kg with a center of mass at G (radius=250mm) and hass a radius of gyration about the pivot O of 295 mm. If the pendulum is released from rest at theta=0º, determine the total force supported by the bearing at the instant when theta=60º. Friction...
I get a larger number for the mass thats resting on the ramp initially than the one that is hanging being held by the cord. Which would make the mass hanging come up to meet the pulley as the larger mass slides down the ramp, wouldn´t it?
the a2 is going down, which is negative so i figured that...
Homework Statement
a 250 pound mass, is released in rest (hanging at 20 ft) and pulls a 400 pound mass up a ramp with a 30º angle, the coefficient of friction between the 400 pound mass and the ramp is 0.5. Determine the velocity as the 250 pound mass hits the ground
