Question
The rod of negligible mass is subjected to a couple
moment of M = (30t²) N·m and the engine of the car
supplies a traction force of F = (15t) N to the wheels,
where t is in seconds. The car starts from rest. The total
mass of the car and rider is 170 kg . Neglect the size of
the car. (Figure 1)
