While researching machines and how they work, Tika finds several online sites that discuss how force and distance are related to work done by a machine. How should Tika most likely describe this relationship between force and distance to her study group?
Jill applies a force of 250 cap n to a machine. The machine applies a force of 25 cap n to an object. What is the mechanical advantage of the machine?
A machine has a mechanical advantage of 4 point 5 What force is put out by the machine if the force applied to the machine is 800 cap n ?
Which statement best describes why a machine is useful?
A machine has a mechanical advantage of 5 What force should be applied to the machine to make it apply 3000 cap n to an object?
Which is a result of using a machine?
Tas watches as his uncle changes a flat tire on a car. His uncle raises the car using a machine called a jack. Each time his uncle pushes down on the jack handle, the car rises up. Tas sketches the jack and labels it using the symbols F, to represent force, and d, to represent distance. He uses large and small letters to compare the sizes of the forces and distances. Which set of labels is correct for the side of the jack that Tas’s uncle pushes on?
What is the mechanical advantage of a machine that applies a force of 1000 cap n to an object when a force of 500 cap n is applied to the machine?
Carlota does 2000 cap j of work on a machine. The machine does 500 cap j of work. What is the efficiency of the machine?
