Problem 2 Dynamics Lab is A 7.75-kg uniform disk developed in the attached to the 4.85-kg slender rod AB by means of frictionless pins at B and C. The assembly rotates in a vertical plane under the combined effect of gravity and of a couple M that is applied to rod AB. Knowing that at the instant shown, the assembly has an angular velocity of 6.00 rad/s and an angular acceleration of 25.0 rad/s², both counterclockwise, determine; Determine: (a) the couple M (b) the force exerted by pin C on member AB 500 mm A 30⁰ 150 mm M OD C B 200 mm

The mass A starts from rest at t = 0 and falls with a constant acceleration of 10.1 m/s?. When the mass has fallen 0.83 m, determine the magnitudes of the angular velocity in rad/s of the pulley. r = 147 mm

A long, straight wire lies along the x-axis and carries current I=55.0 A in the +x-direction. A small particle with mass 4.00 x 10-6 kg and charge 8.00 x 10-3 C is traveling in the vicinity of the wire. At an instant when the particle is on the y-axis at y = 9.00 cm, its acceleration has components a = -5.00 x 103 m/s² and ay = +9.00 x 103 m/s² Part A ۵ At that instant what are the x- and y-components of the velocity of the particle?
