As a torque activity, your Physics TA sets up the arrangement shown below. m1 m2 A uniform rod of mass m, 251 g and m2 163 g and length L 100.0 cm is attached to the wall with a pin as shown. Cords are attached to the rod at the r, 10.0 cm and r, 90.0 cm mark, passed over pulleys, and masses of 187 g are attached. Your TA asks you to determine the following. (a) The position r, on the rod where you would suspend a mass m, = 200 g in order to balance the rod and keep it horizontal if released from a horizontal position. In addition, for this case, what force (magnitude and direction) does the pin exert on the rod? Use standard angle notation to determine the direction of the force the pin exerts on the rod. Express the direction of the force the pin exerts on the rod as the angle 0-, measured with respect to the positive x-axis (counterclockwise is positive and clockwise is negative). r3 m %| F. N (b) Let's now remove the mass m, and determine the new mass m, you would need to suspend…

A block of mass m1 = 2.05 kg and a block of mass m2 = 6.40 kg are connected by a massless string over a pulley in the shape of a solid disk having radius R = 0.250 m and mass M = 10.0 kg.The fixed, wedge-shaped ramp makes an angle of ? = 30.0°as shown in the figure. The coefficient of kinetic friction is 0.360 for both blocks. a) Draw force diagrams of both blocks and of the pulley. b) Determine the acceleration of the two blocks. (Enter the magnitude of the acceleration.) c) Determine the tensions in the string on both sides of the pulley.
Work energy. 2. Figure 2 shows the model of a hammer mechanism comprising an impacting collar of mass m = 4 kg that can freely slide on a vertical rod. The collar is initially held at a height h = 1.2 m. A spring of stiffness k = 6 kN-m' and free length l, = 1.5 m is attached to the center of the collar at one end and the base at the other. The attachment to the base is at a distance L = 1.2 m as shown and located so that, when the collar contacts the base, the spring is horizontal. At the instant shown, a force F = 100 N is applied to the collar that is then released. Determine the velocity of the collar when it hits the base structure. Rod Collar L.

A plank with a mass M = 6.00 kg rests on top of two identical, solid, cylindrical rollers that have R = 5.00 cm and m = 2.00 kg. The plank is pulled by a constant horizontal force Fs of magnitude 6.00 N applied to the end of the plank and perpendicular to the axes of the cylinders (which are parallel). The cylinders roll without slipping on a flat surface. There is also no slipping between the cylinders and the plank. a.

When the rod is perfectly horizontal, the angle 0 = 0, the displacement y 0, and the springs are in neither tension nor compression. Gravity acts on the system (e.g. on mass M). We assume that y is a small displacement. A mass M is attached at the end of the rod.
