The shown collar has a mass of 1.4 kg and moves along the smooth vertical rod defined by the equation de =1.4 rad/sec and dt de = 0.25 rad/sec. r=2.0 0 m with e in rad. Knowing that at this instant 0-45°. a, =-2.579 m/s and ag=8.233 m/s Note: Angle u is the angle between positive unit radial and positive unit tangent vectors with w=38.15°

For the circular thin plate with a square hole as shown in the image below, its radius R = 0.32 m and the side of the square /= 0.18 m, and the material has a mass per unit area of 12 kg/m². If at the instant shown, it is subjected to a force P = 30 N, and has a counterclockwise angular velocity of W = 4.2 rad/s, determine magnitude of the support reaction at point O at this instant. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. Take g = 9.81 m/s². R @ Your Answer: Answer units P

The system below shows a system consisting of 4 masses that are turn. If R₁= R₂ = R3 = R4 = RA = RB = 10, determine the MA and MB placed in field A and field B.

Hi, how do you solve this question?

N= 11.03N F= 25 N

Use work and energy to calculate the final angular velocity (e) of the 10kg bar. The bar has the initial motion shown and displaces 0 = 90°. 2m 3 radis

ω F A 2 kg ball with radius 9 cm and radius of gyration of 7 cm is moving to the right at 2 m/s while a 5 N force is applied, accelerating its motion. It is currently backspinning (and therefore slipping) at w = 4 rad/s, with μk = 0.3. Find the acceleration of the balls center and also the angular acceleration of the ball at this instant a = m (positive right) $2 rad απ (positive $2 CCW)

A force P of magnitude 5 N is applied to a tape wrapped around the body indicated. The body rests on a frictionless horizontal surface. Assume the mass of the thin hoop to be 2.4 kg. 24 A C Determine the acceleration of Point B. The acceleration of Point B is 2.083 m/s². B P x

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.
