(Solution) - Three 2 in radius pulleys and supports two blocks as shown -(2025 Original AI-Free Solution)
Paper Details
A cable passes around three 2-in.-radius pulleys and supports two blocks as shown. Two of the pulleys are locked to prevent rotation, while the third pulley is rotated slowly at a constant speed. Knowing that the coefficients of friction between the cable and the pulleys are ?s = 0.20 and ?k = 0.15, determine the largest weight A
W which can be raised
(a) If pulley C is rotated,
(b) If pulley E is rotated.
