Grade 1 Mechanical Technologist Study Guide
Which welding process is most commonly used for small pipe maintenance
welding? Correct Answer - Oxyacetylene gas welding
What is the proper definition of an engine? Correct Answer - It is a machine
designed to convert energy into useful mechanical motion
What is wet stacking and how can it be prevented? Correct Answer - It is unburned
fuel collecting in the exhaust due to light or no load conditions.
To check flywheel face runout, where should the dial indicator be positioned?
Correct Answer - The base on the bell housing and pointer on the flywheel face.
If a 38-tooth gear running at 360 rpm is driving another gear at 144 rpm, what is
the number of teeth on the driven gear? Correct Answer - Solution: driver Gear x
Driver RPM=Driven Gear x Driven RPM
38 x 360 = N x 144
13,680 = 144N
13, = 144N / 144
95 = N
(95 Tooth Gear
