The mechanical advantage of an inclined plane is always
lesser than 1
equal to one
greater than 1
cannot be determined
Select the incorrect statement :
(a) A machine always has the efficiency less than 100%.
(b) The mechanical advantage of a machine can be less than 1.
(c) A machine can be used as a speed multiplier.
(d) A machine can have the mechanical advantage greater than the velocity ratio.
When the effort arm is greater than the load arm then mechanical advantage is greater than one.
