MC Rectangular plates
Two rectangular plates are hinged together and held by a wire extending from corner C to corner B. The tension in wire BC is 485 N. You want to examine the rotational effects of the tension force in the wire applied at corner C of the plate about the origin of the coordinate system, O.

A uniform rectangular 600 N sign 0.6 m tall and 2.0 wide is held in a vertical plane, perpendicular to it wall by a horizontal pin through the top inside corner and by a guy wire that runs from the outer top corner of the sign to a point on the wall 1.5 m above the pin. Calculate the tension on the wire and the force exerted by the pin.

Plates OABC with weight 500 N is being held by two ropes that
connects to point D. The tension in rope BD and CD each are 310 N
and 270 N. Determine an equivalent system of force and coupled
about point O and also the angle between the ropes.

Two very large thin conducting plates with the same magnitude charge, but opposite sign, are held near each other. The plates are large enough and close enough together that fringing effects near the edges can be ignored (that is results of the Gauss' law for "infinite" plate apply) The two plates are a distance D apart. The surface area of the face of each plate is A, the total charge on each plate is and -o, and the resulting uniform...

A rectangular loop has dimensions 0.505 m by 0.260 m. The loop
is hinged along the x-axis and lies in the xy-plane (see the figure
below). A uniform magnetic field of 1.45 T is directed at an angle
of 40.0° with respect to the positive y-axis and lies parallel
everywhere to the yz-plane. The loop carries a current of 0.855 A
in the direction shown. (Ignore gravitation.)
