![]() ![]() No work is done if the object does not move. We could calculate the function at a few points and add up slices of width x like this (but the answer. Mechanical advantage of crowbar c.the work done by the effort d.distance the load is raised e.the work done on the Load f. And as Wikipedia states, if we were to graph the force in relationship to its position, we would find that it’s. This means that the force to stretch a spring is proportional to the distance the spring is stretched. ![]() work: A measure of energy expended in moving an object most commonly, force times displacement. A man loses a 2.5 M long crowbar to raise a 100 kg mass such that load arm is 0.5 CM the distance moved by the effort is 0.1 M find a.effort needed to lift a load B. Then we will discuss Hooke’s Law, which measures the force required to maintain a spring stretched beyond its natural length.The SI unit of work is the joule non- SI units of work include the erg, the foot-pound. Integration approach can be used both to calculate work done by a variable force and work done by a constant force. Please follow the comment Question: Workdone integrate a to b F(r(u)) dot r(u) du. The work done by a constant force of magnitude F on a point that moves a displacement d in the direction of the force is the product: W Fd. \) is equal to the elastic potential energy stored in spring. It seems like it doesnt make sense to integrate the force again. ![]()
