A3.5 kg book is sitting at rest on a table. what is the value of the normal force being exerted by the table on the book?

This is 3.5 * 9.8   (where 9.8 ms-2 is the acceleration due to gravity).

= 34.3 Newtons ( answer).

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.
