Static And Dynamic Coefficients

Solution :
Given that :
Mass of pipe ( m ) = 500 kg
Static and dynamic coefficients of friction between the pipe and the truck( μs ¿ = 0.4
Dynamic coefficients of friction between the pipe and the truck( μk ¿ = 0.35
Constant acceleration ¿ ¿)
Considering value of g = 10 m/s2
We know that :
F (Force) = ma --(i)
Ffr=N μs -- (ii)
(a) the free body, kinematic and kinetic diagrams of the pipe and the 20% truck
bed showing all the operating acceleration vectors, forces and moments.

(b) the relevant kinetic and kinematic 20% relationships with respect to a global
reference axes system
Solution
Torque = Iα=m R2 α
