Machines 01:19

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. One example of a machine is the cutting plier, which is used to cut wires by applying forces to its handles. When equal and opposite forces are exerted on the handles of the cutting plier, they cause the cutting edges to come together and apply equal and opposite reaction forces on the wire, which are greater than the applied forces.
A free-body diagram of the...

Machines: Problem Solving II 01:30

668

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. Consider a lifting tong carrying a 100 kg load. It comprises movable sections DAF and CBG linked together with member AB.

Assuming the structure is symmetrical at point E, the force acting on member AB can be calculated.
First, a free-body diagram indicating the forces acting at point E is considered. The weight of the load that equals the mass times the acceleration...
