uring the start of a light aircraft engine, one of its propellers rotates 120 revolutions in 4 seconds before reaching constant operating speed. Assuming that the propeller accelerates uniformly during start, determine the acceleration during start and the angular velocity. operational.

The crank and connecting rod of a theoretical steam engine are 1.5 m and 3 m long respectively. The crank makes 180 r.p.m. in the clockwise direction. When it has turned 50° from the inner dead centre position, determine : 1. Velocity and acceleration of the piston 2. Angular velocity and angular acceleration of the connecting rod

Problem 3 At the instant when 0 = 36.87°, the body of the satellite rotates with angular velocity of wi = 1.5 rad/s and angular acceleration of 2 rad/s. Simultaneously, each solar panel rotates with angular velocity of w2 = 2 rad/s and angular acceleration of 1 rad/s, both measured relative to the body of the satellite. • Determine the angular velocity vector wsp of the solar panel. Determine the angular acceleration vector asp of the solar panel. • Determine the position vector rao of point B.

Two shafts the axes of which intersect but are inclined to each other at 22 degree are connected by means of a universal joint. At what position in the rotation cycle of the drive shaft (i) velocity ratio will be maximum, minimum and unity (ii) the acceleration is maximum

8. 2) Rods AB and BC are linked at Band have weights of 18 lb and 37 lb, respectively. The 8-lb collar C, which is connected to BC and the spring, slides freely along the smooth vertical guide. The lengths of the rods are 4 = 1.4 ft and 2 = 2.9 ft. If the system is released from rest when 0 = 0°, determine the magnitude of the angular velocity (in rad/s) of rod BC when 0 = 90°. The attached spring has spring constant k = 20 Ib/ft, and is unstretched when 0 = 0°. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. Take g= 32.2 ft/s2. k CO Your Answer: Answer

A simple friction drive consists of two disks A and B. Initially, disk B has a clockwise angular velocity of 590 rpm, and disk A is at rest. Disk B is known to stop in 69 seconds, decelerating constantly. However, instead of waiting for both disks to be at rest before bringing them into contact, disk A is given a constant angular acceleration of 3.5 rad/s2 counterclockwise. a) Determine the time, in seconds, in which both disks can be brought into contact without slipping. A 2.5 in. Fuente: Beer, 11th Ed. B 3 in. b) Determine the angular velocity of disk A, in rpm, when contact is made without slipping. c) Determine the angular velocity of disk B, in rpm, when contact is made without slipping.

3. The hydraulic cylinder Cextends and causes the collar A to move and accelerate to the left. 3) If the length /= 1.5 ft, the angle 0 = 36°, the linear velocity of collar A, Va is 3.2 ft/s, and the linear acceleration of collar A, aa is 2.4 ft/s?, determine the magnitude of the angular velocity, WAB, of rod AB. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. y Your Answer: Answer units

NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A simple friction drive consists of two disks A and B. Initially, disk B has a clockwise angular velocity of 550 rpm, and disk A is at rest. It is known that disk B will coast to rest in 65 s. However, rather than waiting until both disks are at rest to bring them together, disk A is given a constant angular acceleration of 3 rad/s² counterclockwise. A 2.5 in. B 3 in. Determine at what time the disks can be brought together if they are not to slip. (You must provide an answer before moving to the next part.) The disks can be brought together at t= S.
