In an input of 100 J in a pulley system increases the potential energy of a load by 60 J , what is the efficiency of the system? Explain the physics of perpetual motion machines. What is constraint relationship in context of multiple pulley system?
Yes, the equation for Two Blocks and a Pulley can be rearranged to solve for the acceleration of the blocks. This can be done by dividing both sides of the equation by the total mass of the system (m1+m2). The resulting equation is a=(m1-m2)/m1+m2, where a is the acceleration of...
While what I did gets the proper result (and I know it to be commonly used to solve these inextensible rope pulley system problems), what is the idea that lets us say the constraint L the length of the rope - something which is always positive as far as I can tell can be added in...

In the RT experiments, the same rail system is used however instead of impacting a spring the tank is accelerated downward using a weight and pulley system. The resulting fluid flows are primarily observed using backlit imaging. The initial perturbations are either forced (by oscillating the tank...

The pulley is assumed to have no mass and no friction, allowing for easier analysis of the system's motion. How does the mass of the blocks affect the system? The mass of the blocks affects the acceleration of the system. According to Newton's second law, the acceleration of an object ...
