Problem I

A fixed crane has a mass of 1000 kg and is used to lift a 2400-

kg crate. It is held in place by a pin at A and a rocker at B. The

center of gravity of the crane is located at G. Determine the

components of the reactions at A and B.

Problem II

The frame shown supports part of the roof o a small

building. Knowing that the tension in the cable is 150

kN, determine the reaction at the fixed end E.

Problem III

Determine the magnitude the tension in the supporting cable

and the magnitude of the force on the pin at A for crane

shown. The beam AB is a standard 0.5 m with a mass of 95 kg

per meter of length.

Problem IV

The 450 kg uniform I beam supports the load

shown. Determine the reactions at the

supports.

Problem V

Determine the force magnitude P requerid to

lift one end the 250 kg crate with the lever

dolly as shown.

Problem VI

Two crates, each of mass 350 kg, are placed as

shown in the bed of a 1400-kg pickup truck.

Determine the reactions at each of the two (a) rear

wheels A, (b) front wheels B.

Problem VIII

The bracket BCD is hinged at C and attached to a

control cable at B. For the loading shown, determine

(a) the tension in the cable, (b) the reaction at C.

Problem IX

A lever AB is hinged at C and attached to a control

cable at A. If the lever is subjected to a 500-N

horizontal force at B, determine (a) the tension in the

cable, (b) the reaction at C.

Problem X

Neglecting friction, determine the tension in

cable ABD and the reaction at support C.
