2. Load between effort and fulcrum.
3. Effort between fulcrum and load.
4. Load and effort acting at the same point.

Class II levers are designed to have:

1. M.A. = V.R.
2. M.A. > V.R.
3. M.A. > 1
4. M.A. < 1

Which class of levers have effort and load on the same side of fulcrum

1. Class I lever
2. Class II Lever
3. Class III Lever
4. Class II or class III Lever

A bottle opener is an example of:
