Question

How do simple machines change the direction of force?

Answer 1

Hint : In this question we have to find the way the simple machines change the direction of force. From his first we will understand what simple machines are and what they do. Then we will see how simple machines change the direction of force.

Complete Step by step answer:
Pulleys, lever etc. are examples of simple machines. These machines use pivot points to balance forces. Now we will understand the forces acting on the simple machines.
By Newton’s second law of motion the force is given by;
F=ma
 Above formula shows that if the forces are not in balance then there will be some acceleration.
Now we will find work done, W=F. d
Power applied in the machine is given by following formula:
$Power={\displaystyle \frac{energy}{time}}$
For a machine to be in balance we will use following relation:
$$F_1.L_1=F_2.L_2$$
So from above we can see that simple machines change the direction of force depending on the mass and acceleration.
Result- Hence, from the above explanation it is clear that the simple machines change the direction of force depending on the mass and acceleration of the objects in the machine.

Note- Hence, in such types of questions we need to understand the process that is happening in the system. Simple machines include pulleys, levers, ball bearings etc. these machines consist of many more components like weight, blocks etc. These machines are used to create systems to find the tension, force in the string of the system. These machines make the system easier to operate and easier to find the parameters as well.
