6 Write down an expression for the velocity ratio of a pair of gear wheels.
What is the number of teeth in the driving wheel if the driven wheel has
60 teeth and the velocity ratio of the gear is 0.4? Why is this gear not
powerful to move a heavy car from rest?
No of teeth in the driven wheel
Hint: V. R.=
No of teeth in the driving wheel​

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
