Question
Q2. Figure Q2 shows a simple gear train. At the instant shown, a force F = 1100 N is
applied at one end of a 0.175 m long lever, perpendicular to the length of the lever.
The other end of the lever is attached to shaft 1, and so the lever turns shaft 1. Gear
A is attached to shaft 1 and has 48 teeth, Gear A is meshed with gear B, which has
16 teeth.
a) What is the gear ratio from gear A to gear B?
The efficiency of power transmission between the two gears is 70%. The moment
of inertia of shaft 1, including the lever and gear A is 1.05 kgm² and the moment of
inertia of gear B is 0.15 kgm². The frictional torque on shaft 1 is 0.2 Nm and the
frictional torque on gear B is 0.7 Nm. If, at the instant show, the lever is moving
downwards with a velocity of 1.4 m/s and an acceleration of 0.15 m/s², determine:
b) the torque transmitted to gear A.
c) the torque transmitted to gear B.
d) the power transmitted to gear B.
