Answer 2

Answer:

• As mechanical advantage is a simple ratio of two distance is it also doesn't have the unit to the friction is not involved in its efficiency of a simple machine is defined as the ratio of useful work done by a machine to the total work put into the machine.
• velocity ratio will not change for a machine of a given design it is the ratio of velocity of effort to the velocity of load is called as the velocity ratio of the machine.
