Question

which of the following describes which simple machine cannot do?
i) increases the amount of force applied
ii) increases the speed of doing work
iii) changes the direction of applied force
iv) no displacement occurs​

Answer 1

Answer:

if I am not correct then sorry

Explanation:

no displacement occurs

Answer 2

Option 1) increases the amount of force applied

increases the amount of force applied simple machine cannot do.

• You cannot give a machine more energy than you already give it. So why would one need a basic machine. A basic machine can alter the amount of force you must apply to an item as well as the distance across which you apply the force, but it cannot alter the amount of work you must accomplish.
• Contrary to popular assumption, using machines does not result in more work being done. They merely alter the method of operation. By increasing the amount of force applied, extending the distance over which the force is applied, or altering the force's direction, machines facilitate work.
• The equipment doesn't make you work harder or with more force. The amount of force you apply to an object is the same amount of force the machine applies to it. Making you stronger doesn't "assist" you in any way.
• Any of a number of devices with few or no moving components that are used to change motion and the strength of a force in order to do work are considered simple machines. They are the most basic systems that have ever been found to increase force by leverage (or mechanical advantage).
