The smooth disks D and E have a weight of 220 lb and 100 lb, respectively. If a horizontal force of P = 220 lb is applied to the center of disk E, determine the normal reactions at the points of contact with the ground at A, B, and C.

3. Determine the force components acting on ball joint A, the reaction at roller B, and the tension in the CD string necessary for the balance of the quadrant plate circular

Four forces are exerted on the eyebolt as shown. If the net effect on the bolt is a direct pull of 610 lb in the y-direction, determine the necessary values of T and e. Assume F₁ = 315 lb, F₂ = 295 lb, F3 = 390 lb, d = 30° F₁ Answers: T = e= i i lb O T Ф

A cable is attached to the structure at E, passes around the 0.1-m diameter, frictionless pulley at A, and then is attached to a 1000-N weight W. Determine the magnitudes of the horizontal and vertical components of force pin at F. Assume the wall at G is smooth. MUST DRAW ALL THE FREE-BODY DIAGRAMS. W 1 m. B m Im
