coefficient of static friction, us. Assuming that both blocks are in impending motion to the
left, draw two separate free-body diagrams of block A and block B.
Tutorial 5.3: Friction
1. If a horizontal force of 50 N is required to start a 15 kg block moving on a horizontal
surface, what is the value of the coefficient of static friction?
21 kg

rough surface
2. Determine the mass of a block if a horizontal force of 20 N is required to start it moving
on a horizontal surface where the coefficient of static friction is 0.34.
6. Blocks A and B are staked together as shown. Block A is connected to a wall by a taut
string, while block B is subjected to a force, P, acting along the slope. The coefficient of
static friction at both rough surfaces is us. Assuming that block B is in impending motion
3. A block of mass 40 kg rests on a rough surface with a coefficient of static friction, He =
down the slope, draw two separate free-body diagrams of block A and block B..
0.21, if the block has an impending motion to the left, draw its free body diagram and
calculate the friction force present.

4. A block of mass 20 kg rests on a horizontal surface and the coefficient of static and kinetic
friction between the two surfaces are 0.33 and 0.25, respectively. Calculate the following:
a. The horizontal force required to start moving the block.
b. The kinetic friction force.
