CDEFGH is plate with a circular hole in it and has a unit weight p (N/m2). It is attached on DE beam with weld. A crate has a weight of W (kN) at A is linked to the plate from C by the help of a cord. The surface under the crate has a coefficient of static friction µ, and the pulley has a coeficient of static friction µ2. a) Find the center of the gravity of the CDEFGH plate according to O (given in grey color in the figure). HCD is half circle centered at O. • A full circle centered at O is removed from the plate. • HOD line and EF line are vertical. b) What should be the minimum weight of the box at A in order to prevent the movement of the plate to downward. c) What are the support reactions at K.

A person is sitting with one leg outstretched and stationary, so that it makes an angle of 30.0° with the horizontal, as the drawing indicates. The weight of the leg below the knee is 34.5 N, with the center of gravity located below the knee joint. The leg is being held in this position because of the force M→ applied by the quadriceps muscle, which is attached 0.100 m below the knee joint (see the drawing). Obtain the magnitude of M→.

The Cylinder weighs 1000 kg, rest on an plane which is inclined at 34° from the horizontal. The normal force acting on a plane to the cylinder is 10 KN. Assume smooth surface, the cylinder leaned to a vertical rod of 8m long and has a weight of 5 KN which was supported by a cable and a hinged (as shown). Find the tensile force of the cable holding the rod and the reactions of hinged to support the cylinder from sliding.
