Q2. Each of the two blocks in Figure 10.4 has a mass of 10 kg, and the coefficient of friction between the block is 0.40 and between the blocks is 0.33. 10 kg (a) Determine graphically the force Fp required to pull one block from under the other. (b) Repeat (a) but assume that a lubricant between the blocks has been added to reduce 10 kg the friction by 150%. (c) Assume that the thread connecting the block to the wall is cut. What is the minimal force Fp required to move the block?

Q2.
mass of 10 kg, and the coefficient of friction between
the block is 0.40 and between the blocks is 0.33.
Each of the two blocks in Figure 10.4 has a
10 kg
(a) Determine graphically the force Fp required to
pull one block from under the other.
10 kg
(b) Repeat (a) but assume that a lubricant
between the blocks has been added to reduce
the friction by 150%.
(c) Assume that the thread connecting the block to the wall is cut. What is the minimal force Fp
required to move the block?
For all graphical solutions please indicate all angles needed to construct the force polygons and
directions of the forces. Also show the scale used.
