Consider a block at rest on a fixed horizontal surface, say, or tabletop. one force acting on the block is its weight, or the force of gravity. however, the fact that the block remains at rest that there must be another force on it to balance the weight. Name and state the law used above to deduce the existence of this force?

answer is c

explanation:

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
