Physics 10th ICSE: Machines [Semester 1]

Question 1

What is a Machine?

Answer 1

A device by which we can either overcome a large load by applying smaller effort at a convenient point

Question 2

Define the term ‘Load’.

Answer 2

Resistive or opposing force to be overcome

Question 3

Define the term ‘Effort’.

Answer 3

The force applied on the machine to overcome the load

Question 4

Define the term ‘Mechanical Advantage’.

Answer 4

The ratio of load to effort

Question 5

Can a machine be used as a force AND speed multiplier simultaneously? Why?

Answer 5

No dumdum-

For a machine used as force multiplier,
Effort < Load

Whereas, for a machine used as speed multiplier,
Effort > Load
