MECHANICAL REASONING QUESTIONS & CORRECT
ANSWERS
1. A)Post
Which post holds up the greater part of the
A
load? A- Post A
The weight is distributed more on B- Post B
the side of post A, Therefore, C- Both equal
it
D- Not clear
is holding up the greatest
part of the load.
2. C)Neither of the other gears The single lobe on cam A will
cause the setscrew to hit the
Because of the way the gears con-
are meshed, both gear 1
and gear 3 will move in the
opposite direc- tion of gear
2.
3. A)A
Pulley A is the smallest
gear. Therefore, it must
turn faster (make more
revolutions per minute).
