1
Q
What is mechanical advantage and what is the formula?
A
Mechanical advantage is how much a force is increased when using a tool or machine.
Ma= load ÷ effort
2
Q
What is work and what is the formula?
A
Work is the exertion of a force, so it overcomes resistance.
work=effort×distance moved
3
Q
What is the velocity ratio and what is the formula?
A
Velocity ratio is when the effort and load move at the same time, but the effort moves twice as far. The difference between them is called velocity ratio.
velocity ratio= distance effort moves÷distance load moves
4
Q
What is torque and what is the formula?
A
Torque is the turning force of a lever. You can get more torque with a lever with a longer handle than a short one
Torque=effort×distance
