A 30 Kg cubic block, of side length 300 mm, slides down a lubricated plane with a slope of 30? . The lubricant has an absolute viscosity of 2.3x10^-3 N.s/m^2.
Q) Determine the speed of the cubic block down the plane when in equilibrium.Hence determine the total force required to pull the cubic block up the plane at the same speed.
given:
speed of block = 21.32 m/s
Total force to pull block up plane = 181.6 kN
