What forces contribute to density
1 answer:
No force contributes to density, the density is a physical quantity that is defined as being 
the raport between the mass of the object and its volume. However if you want to measure the density of an object you might want to determine its gravity force (weight) 
from which knowing the gravitational acceleratin you can find its mass

let the distance of pillar is "r" from one end of the slab
So here net torque must be balance with respect to pillar to be in balanced state
So here we will have
here we know that
mg = 19600 N
Mg = 400,000 N
L = 20 m
from above equation we have
so pillar is at distance 10.098 m from one end of the slab
