Question
1. For this series of 4 questions, a rider rides in a car that is connected to a 4-m rod,
and rotates about the z axis. The rod of negligible mass is subjected to a constant
couple moment of M, and the engine of the car supplies a traction force of F.
Neglect the size of the car. You will be asked to solve for different things. Please pay
attention: the numbers may change from problem to problem since they are
randomized.
3) If the rod is subjected to a constant couple moment of M = 800 N•m, and the
engine of the car supplies a traction force of F=11•t N to the wheels, where tis in
seconds, what is the magnitude of the angular impulse from the moment and the
force to the car-rider system in kg•m²/s from t = 0 to t = 5.7 s? Your answer must
include 1 place after the decimal point.
Your Answer:
Answer
M
4 m
F

Your answer must include 1 place after the decimal point. Your Answer: Answer M 4 m F
4) If the total mass of the car and the rider is 160 kg, the rod is subjected to a
constant couple moment of M = 660 N•m, and the engine of the car supplies a
traction force of F=14• t N to the wheels, where tis in seconds, determine how
much time it will take before the speed of the car reaches a speed of 5.3 m/s if the
car starts from rest. Your answer must include 2 places after the decimal point and
the proper unit.
