Unformatted text preview: O 1 is 6 rad/s 2 . (a) Find the belt velocity. υ b = ________ 1.2 m/s ____________ (b) Find the belt acceleration. a b = ________ 3.6 m/s 2 __________ (c) Find the acceleration of B . a B = ________ 4.02 m/s 2 __________ 3. A spinning blade is 1.6 m long and is pivoted at its center. At t = 0 s, the normal acceleration at the tip of the blade is 5 m/s 2 . The blade is rotating with a constant angular acceleration, and when t = 6 s the blade rotates through an angle of 24 rad. Find the speed at the tip of the blade at t = 6 s. ________ 4.4 m/s __________ 8 m 3 m O 30° F 1 = 150 N F 2 = 100 N 4. Find the total torque about the pivot O by the two forces F 1 and F 2 on the angled rod. Also indicate the direction of the total torque. ________ 250 N·m _ CCW _________...
