The figure shows a man lifting a heavy rock using a steel bar. He pushes downwards on the end of the bar with a force F. Which pivot positions allows the force F to be as small as possible?

calculate the moment

In a balanced seesaw the total clockwise moment = total anticlockwise moment .True or False

Which letter shows where you should apply the effort?

Which letter is the pivot?

How to calculate moment ?

[True or False] Weight = mass x gravitational force

Calculate the moment!

How is the principle of moment help in making the beam balance?

Define " Moment "

[True or False] equilibrium is unbalanced

[True or False] Gravitational force on Earth is 10 N/kg
