Figure 1-10 Friction vs. Applied Forces
Another Strategy Consideration
Figure 1-9 shows that the SumoBot can exert its highest force of friction just before losing
traction. After it starts slipping, it can't push as hard against its opponent because its treads
only have kinetic friction to rely on.
Problem: You had to apply 5 lb of force to make an object that weighs 10 lb start to slide
on a surface. What is the coefficient of friction?
Solution: Use the µ
S
equation and substitute 5 lb for f
S, Max
and 10 lb for N.
