The 160-lb exerciser is beginning to execute a bicep curl. When in the position shown with his right elbow fixed, he causes the 20-lb cylinder to accelerate upward at the rate 0.30g. Neglect the effects of the mass of his lower arm and estimate the normal reaction forces at A and B. Friction is sufficient to prevent slipping. B A <12" 12" 16" 19° 57" 20 lb
set up and solve the equations of motion using rectangular coordinates the 3-kg collar shown has a coefficient of kinetic friction uk=0.22 with the shaft. the spring is unstretched when s=0 and the collar is given an initial velocity of v0=19.5 m/s. the unstretched length of the spring is d=1.5m and the spring constant is k=597 N/m. What is the acceleration of the collar after it has moved 1.5m?
A block of mass m₁ is suspended from the ceiling with a spring k and damper b. Attached to the block is a massless rod of length L. Affixed to the end of the rod is a point-mass of mass m₂. Gravity is acting in the direction indicated in the figure. Use the energy method to set up the energy expression you would use to calculate the equations of motion for the system. Hint: be sure to decompose the velocity of the pendulum into horizontal and vertical components. DO NOT CALCULATE THE EQUATIONS OF MOTION, only setup the energy expression. x(t) b 7 m₁ e(t) (m₂
Dynamic Lecture: The 2 kg BC ring can only move left and right on the frictionless rigid arm. Ring BC is connected to springs with spring constants k = 300 N / m and k ′ = 200 N / m at points AB and CD. The unstretched length of both springs is 600 mm. Since it is known that the springs are not tensioned and starts from rest, find the velocity of the ring BC at the moment when the external force F is applied 200 mm.

Block A rests on a horizontal tabletop. A light horizontal rope is attached to it and passes over a pulley, and block B is suspended from the free end of the rope. The light rope that connects the two blocks does not slip over the surface of the pulley (radius 0.080 m) because the pulley rotates on a frictionless axle. The horizontal surface on which block A (mass 2.50 kg) moves is frictionless. The system is released from rest, and block B (mass 5.00 kg) moves downward 1.80 m in 2.00 s. A)What is the tension force that the rope exerts on block B ?B)What is the tension force that the rope exerts on block A ?
The mass of the ball is m = 20 kg and the length of the light rod is /= 0.52 m. The ball-rod assembly is free to rotate about a vertical axis through O. The carriage, rod, and ball are initially at rest with 0 = 0 when the carriage is given a constant acceleration ao = 5.4 m/s². Write an expression for the tension T in the rod as a function of 0 and calculate T for the position 0 = TT/2. Answers: T = i - ! N
The slender bar AB with a mass of 60 kg and a length of 4 m is secured by a cable at C, and pivoted to the back of a truck at A. When the truck starts from rest creating an acceleration of 5 m/sec² on the bar in the direction of the arrow, calculate the magnitude of the tension in the cable.

A cart has a mass of 1.5 kg. It is given some initial push toward a sensor and is slowed by a hanging mass which makes the cart turn around and speed up as it returns to its original position. This situation is illustrated in the attached image. If the acceleration towards the sensor is 0.5 m/s2 and the accaleration away from the sensor is 0.15 m/s2, a. draw the free body diagrams for the cart moving towards the sensor and away from the sensor. b. Write Newton's law for both situations and solve for the frictional force and for the force from the hanging mass.
Part A The system is released from rest at 0= 0° when a constant couple moment M = 100 N·m is applied. (Figure 1) If mass of the cable and links AB and BC can be neglected, and each pulley can be treated as a disk having a mass of 6 kg, determine the speed of the 20-kg block at the instant link AB has rotated 0-90°. Note that point C moves along the vertical guide. Also, the cable does not slip on the pulleys. Express your answer to three significant figures and include the appropriate units.
