The disk with a diameter of 20cm and a mass of 300g and the border of a disk-shaped object with a diameter of 30cm and a mass of 600g are interlocked. Apply a force of 9 N to the outer circumference of the small disk and rotate the two plates together. Find each torque applied to the small disk and the torque applied to the large disk.

Deltoid Axe Shoulder joint Before throwing, I hold the 1.5-pound (0.67-kg) axe out in front of me at arm's length, the axe's center of mass being 75 centimeters from my shoulders. What torque does the axe exert about the axis of my shoulder? b. My deltoid is connected to my upper arm 15 cm from the shoulder joint, pulling at an angle 30 degrees from the arm. What force does the deltoid need to exert in order to hold the axe out in front of me? What third force must be exerted by the surrounding shoulder joint, in order to hold my arm out like this? Include a quick picture, showing direction!

The plant in the picture has mass of 29 kg, and is hanging at a distance of 1.4 meters from the wall. The horizontal rod has mass of 6.2 kg. Assume that its weight is evenly distributed, therefore it can be treated as a single force at the center of mass. The rod is 2 meters long, and there is a cable at a 23° angle supporting it at the end. Center of mass of rod from the point = 2/2=1m Using the wall as the axis of rotation, find the magnitude of the downward torque, from both the weight of the rod and the weight of the plant. t=458.64Nm a.The downward torque is balanced by the upward torque from the force of tension. Find the magnitude of the force of tension. T=?N b.F is the contact force between the rod and the wall. Using the other horizontal force in the problem, find the horizontal component of F (the normal force) that must be present for the rod to be at equilibrium. Fx=?N c.There is a vertical force from a component of the tension, but this is not enough to balance the…

Consider a wheel with four spokes as shown below. The radius of wheel is r = 0.18 m. The mass of the circumferential part is 0.7 kg, and the mass of each spoke is 0.12 kg. If one of the spokes is removed, calculate the distance (in mm) between the old and new center of mass locations. r
