An object, moving along the
circumference of a circle with radius R, is acted upon by a force
of constant magnitude F. The force is directed at all times at a 30
angle with respect to the tangent to the circle as shown in the
figure .
Determine the work done by this force when
the object moves along the half circle from A to B.
Express your answer in terms of the
variables , , and appropriate constants.

Four forces of equal magnitude but with directions as shown act at the concern of a square. The square has a fixed pivot point p. Rank (from least to greatest) the torque produced by these forces about the pivot point. We define a positive torque as one in the counter-clockwise direction. Tau_1 = Tau_2 = Tau_3 = Tau_4 Tau_1 < Tau_2 = Tau_4 < Tau_3 Tau_1 < Tau_2 = Tau_3 < Tau_4 Tau_4 < Tau_1 < Tau_2 < Tau_3 A...

We have two (2) ystems. System A, consists of two solid cylinders of radius R with both rotating counterclockwise Systems, consists of one solid cylinder of radus rotating dockwise and another solid cylinder of radius 4 rotating countercockwise. All of the cylinders have the same mass, and the same magnitude of angular velocity Determine the system that has the greatest magnitude of angular momentum. ОА They're equal not enough information

2 Three identical cylinders are sealed with identical pistons that are free to slide up and down the cylinder without friction. Each cylinder contains an ideal gas, and the gas occupies the same volume in each case, but the temperatures differ. As shown in the figure, each cylinder is inverted so the piston is below the gas, and the bottom of each piston is exposed to the atmosphere. T-0°C T-50 °C T-100 oC In cylinders 1, 2, and 3 the...
