The iillustration depicts a prototype design for the High-G Rover. It is made up of an arm that is attached to a shaft that is pinned to a disk. The aarm has a retractable shaft that extends and contracts to cause the disk to rotate. To make the computation easier, let us assumee that the arm does nott rotate A. If the arm's total length is L = 640mm, the distance from the centre of the disk to the shaft pin is r = 112mm, and the arm rotates clockwise at a constant angular velocity of 250.273 rpm. 1.) Would an increase in angular velocity increase point C's linear velocity relative to point A? If so, why or why not? a.) What is the linear velocity of point C with respect to point A if the angular position of the pin (between AB and BC) is 0.578 radians? b.)

A space station shaped like a giant wheel has a radius 98 m and a moment of inertia of 5.01 x 108 kg-m2. A crew of 150 lives on the rim, and the station is rotating so that the crew experiences an apparent acceleration of 1 g. When 100 people move to the center of the station for a union meeting, the angular speed changes. What acceleration is experienced by the managers remaining at the rim? Assume that the average mass of each inhabitant is 65.0 kg. m/s2
An automobile driver took a curve too fast. The car spun out of control about its center of gravity (CG) and slid off the road in a northeasterly direction. The friction of the skidding tires provided a 0.25 g linear deceleration. The car rotated at 100 rpm. When the car hit the tree head-on at 30 mph, it took 0.1 sec to come to rest. The force exerted by the 100-lb child on her seatbelt harness as a result of the acceleration just prior to impact is 875 lbf 618 lbf 657 lbf 725 lbf
The arms of a Porter governor are each 250 mm long and pivoted on the governor axis. The mass of each ball is 5 kg and the mass of the central sleeve is 30 kg. The radius of rotation of the balls is 150 mm when the sleeve begins to rise and reaches to certain radius at maximum speed. The governor has radius that is 175 mm at mid position. The speed range of the governor is 38 rpm, and the increment in speeds is constant in the three positions. Find : (1) the friction of the load which existed at the sleeve, and (2) the governor radius at maximum speed. The friction is ignore in mid position only.
