Write net torque and net force equation for a simple seesaw system

Which of the following statement is incorrect? Select one: Friction causes objects to move faster Friction is high for dry surface Friction causes objects to slow down Friction force acts opposite to motion

Why is calculus needed for hydrostatic pressure and force application problems?

What is energy conversion used for ؟

A hydraulic press must be used to press-fit two components together in an assembly process. The system must generate at least 975 lb of force to perform the press fit. The piston at the input cylinder is pushed with a force of 250 lb and has an area of 30 in.2. The output can use up to 15 cylinders that are each 30 in.2. How much mechanical advantage is required to gain the necessary force ?

1. Define a force of 1 newton and 1 pound with the help of a figure.

why is the actual weight is lower than the theoretical weight
