The problem is missing some parts but nevertheless here is
the answer:
Given:
1.7 m long barbell with 23 kg weight on the left and 34 in
the right end.
Solution:
Calculating from the left side:
Center of gravity = ΣM/ΣW = [23*0 + 9*(1.7/2) + 34*1.7]/[23+9+34]
Center of gravity = .992 m from the left end
Answer:
The mass of the second student is 20.180 Kg
Explanation:
When the mass is added on one piston, it causes a change in pressure on other piston.
The change in mass is calculated using the formula,
Δm=ρhA/g
The calculated radius of piston is 0.46 m.
Given h=35 cm= 0.35 m.
Assume ρ=850 kg/m^3
So Δm=850*0.35*π*(0.46)^2/9.8
Δm= 20.180 Kg
