Solution

Mechanical advantage = 8
But mechanical advantage = `"L"/"E"`
Here, L = 2 Kgf
Force applied at the handle of pump plunger = E =?
⇒ M.A. = `"L"/"E"`
8 = `2/"E"`

E = `2/8=1/4`

= 0.25 kgf.

Consider a water tank shown in the figure. It has one wall at x = L and can be taken to be very wide in the z direction. When filled with a liquid of surface tension S and density ρ, the liquid surface makes angle θ(θ << 1) with the x-axis at x = L. If y(x) is the height of the surface then the equation for y(x) is:

(take θ(x) = sin θ(x) = tan θ(x) = `dy/dx`, g is the acceleration due to gravity)
