1@mani........ M.A means jus ulta of ur ans without friction
hope i m correct
When effort is applied parallel to the base of an
inclined plane (angle of inclination θ) its
mechanical advantage is equal to
(a) tan θ
(b) 1/ tan θ
(c) sin θ
(d) 1/ sin θ

11wat is mechanical advantage
aggar friction hai to answer is tanθ (a)
24use this:
mechanical advantage=
(Force exerted by machine on load)/(force used to operate machine)
1we dont have any value for using the above formula
mechanical advantage (MA) is the factor by which a mechanism multiplies the force or torque put into it. (source-internet)
now somebody ans. it
124consider incline plane as load and a machine placed on it
so using that formula we get mg cos theta/mg sin theta => cot theta
=>b)
