3. A machine may simply change the________ of applied force.
4. The force applied on a machine to do somemechanical work is called _________
5. In a machine the output is always
__________than the input.​

Answer 1

Answer:

simple is the correct answer

Answer 2

ANSWER :

[1] The handle of a water pump acts as a simple machine.

• ❒ In a water pump, the handle of the pump acts as a simple machine.

________________________________

[2] The resistance overcome by a machine is called load.

• ❒ Load is the resistance that is overcome by a machine. It is a resistive or opposing force which is to be overcome by a machine.

________________________________

[3] A machine may simply change the direction of applied force.

• ❒ Simply, the direction of applied force may be changed by a machine. A pulley is used generally used to change the direction of applied force.

________________________________

[4] The force applied on a machine to do some mechanical work is called effort force.

• ❒ Effort force is the force that is applied on a machine to do some mechanical work by the machine. By appling effort force in a machine, output work is received.

________________________________

[5] In a machine the output is always less than the input.

• ❒ In a machine, the input work is more than the output work and the output work is less than the input work as some input work is used to overcome friction.
