SOLUTION: 1.) The pointer of a recording voltmeter can travel to the right at the rate of 8 cm/sec. What would be the return rate if the total time for the pointer to transverse the full 10-

Question 987173: 1.) The pointer of a recording voltmeter can travel to the right at the rate of 8 cm/sec. What would be the return rate if the total time for the pointer to transverse the full 10-cm scale and return to zero must not exceed 1.5 sec?
2.) A shaper is set to have a forward cutting speed of 50 ft/min and a stroke of 18 in. It is observed to make 80 cuts (and returns) in 3 mins. What is the return speed?

1.)
It takes the pointer (10cm)/(8cm/sec)= 1.25 seconds to travel full scale to the right, so it must return across the 10cm scale in 0.25 seconds:
10cm/0.25 sec=40cm/sec
ANSWER: The return rate would be 40cm/sec.
