Question
The circular disk lies in the horizontal plane and rotates with a counterclockwise angular velocity of 4 rad/s which is increasing with 10 rad/s2 at the instant shown. The 0.5-kg slider A is supported horizontally by the smooth slot and the string attached at B. Determine the tension in the string and the magnitude of the horizontal force exerted on the slider by the slot.
Explanation / Answer
1. Force analysis
2)2. Kinematics analysis
R = 0.6m
an = Rw^2
m = 0.5 kg
w = 4 rad/s
sigms = 0
at =0
