Given :
An inclined plane is used to lift a box into a moving truck. The ramp is 6 m long and 1.5 m.
To Find :
The mechanical advantage of the inclined plane.
Solution :
Mechanical advantage, M.A of an inclined plane is given by :
Putting given values in above equation, we get :
Therefore, the mechanical advantage of the inclined plane is 4.
Answer:
Both reaches equilibrium simultaneously.
Explanation:
Given that,
First stretch spring= 20 cm
Second stretch spring = 10 cm
Two equal masses are suspended from identical spring.
Their forces constants are equal time period for oscillation
Using formula of time period
Where, T = time period
m = mass
k = spring constant
Time period independent of amplitude.
Hence, Both reaches equilibrium simultaneously.
