3.
Determine the minimum force F needed to push the two 75-kg cylinders up the incline. The force acts parallel to the plane and the coefficients of friction at the contacting surfaces are 
A = 0.3, B = 0.25, C = 0.4. Each cylinder has a radius of 150 mm.

Draw the fbd for given block , consider that two block as one body and write the vector components weight downwards, friction opposite to the applied force F . and indicate the normal reaction to the block .
First of all find the normal reaction by summation of forces along normal line .
we will get normal . multiply normal with static frictional coefficient you will be able to get frictional force.
Take summation of forces along the inclined plane you will get the applied force F.
