Machines are so designed to ___________ and alter the effects of the forces.
The forces acting on the joints and on the members are determined by the simple equilibrium equations, which are used in the usual beams and trusses.
Forces acting on the supports and the joints are not important to determine, in the frames and machines.
The forces obtained at the joints and the members of the machines are very important. They are used for:
There are no free body diagram used in the calculations of the forces at the supports and at the joints. Because the free body diagrams of a machines are so hard to be made.
Which of the following is correct for the frames in 2D and machines in 3D?
If a force applied at any point in its line of action and is still creating the same moment about any fixed point say P, then the force is said to be______________
If a force applied at any point in its line of action and is still creating the same moment about any fixed point say P, then the force is said to be sliding vector. What is the name of this property?
