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.) What is the distance between points A and C if the angular position of the pin (between AB and BC) is 0.578 radians? c.)

Please respond as reply as possible, USE THE DATA SHOWN IN THE TABLE. Distances are in centimeters The mechanism shown is used to carry out experimental tests on different industrial springs that are placed between the wall and point A. The rigid reinforcement that holds the spring at A moves through the horizontal beam by means of the 4 frictionless rollers. The piston CD is compressed by stretching the spring at A. For the situation in the position shown the spring is stretched a distance s and has an elongation constant of 2000N / m. The weight of the system can be considered negligible. Determine: 1.The magnitude of compressive force exerted by the piston at the position shown. 2.The magnitude of the force experienced by the bolt at E.

1. A motor winds the pulley at A with the kinematic quantities given. Find the acceleration of block E at this instant. (Figure difficult? The radius of the wheel B to the fixed rope is 50 mm, while the radius of the wheel attached to A is 125 mm.) I believe the difficulty to this problem, to the degree it is difficult, is in recognizing what you have and putting it into a familiar form. Feel free to contact me to discuss it. 50 mm A-40 rad/s 4-5 rad/² 50 mm B 125 mm
