Bar AB has the angular motions shown. Suppose that WAB = 4.2 rad/s and a AB = 7 rad/s² . (Figure 1) Figure 1 of 1 B 0.5 m OAB 1 m 60 C

In a slider crank mechanism at the given instant member AC is rotating with an angular velocity of 2 rad/sec. Draw the position and velocity diagram of the mechanism and determine the velocity of the slider B

At the given instant, the truck is going around the circular roundabout at a speed of 30 기회 of 20 magnitude of acceleration FAC values for the figure are given in the following table. Note the figure may not be to scale. value 0₁ 70 degrees Using normal and tangential components, Variable a. Determine the magnitude of the tangential acceleration of the truck, a. b. Determine the magnitude of the normal acceleration of the truck, a c. Determine the radius of curvature of the roundabout, p. Round your final answers to 3 significant digits/figures. a= an p= M72 m 7172 E MIL and a

Determine the acceleration at the instant shown. v = 2 m/s i = 3 m/s

At the instant shown, an overhead garage door is being shut with point B moving to the left within the horizontal part of the door guide at a speed of 9 ft/s, while point A is moving vertically downward. Determine the angular velocity of the door and the velocity of the counterweight Cat this instant if L = 6 ft and d= 1.5 ft. (Round the final answers to four decimal places.) L B C floor The angular velocity of the door is k rad/s. The velocity of the counterweight Cis ft/s.
