Question 1
Parallel forces act along lines that are:
- APerpendicular to one another
- BParallel to one another
- CAlways through one point
- DAlways in the same direction
Show answerHide answer
Answer: B
Parallel forces have parallel lines of action; their points of application may differ.
Question 2
Like parallel forces act in:
- AOpposite directions
- BPerpendicular directions
- CThe same direction
- DRandom directions
Show answerHide answer
Answer: C
Like parallel forces are parallel forces directed the same way.
Question 3
Unlike parallel forces act in:
- AThe same direction
- BOpposite directions
- CPerpendicular directions
- DCircular paths
Show answerHide answer
Answer: B
Unlike parallel forces have opposite directions.
Question 4
Two parallel forces act upward on a body. They are:
- AUnlike parallel forces
- BLike parallel forces
- CA couple necessarily
- DNon-parallel forces
Show answerHide answer
Answer: B
Both forces are parallel and point in the same direction.
Question 5
Two parallel forces of 12 N and 7 N act in opposite directions. Their resultant magnitude is:
- A19 N
- B84 N
- C5 N
- D12 N
Show answerHide answer
Answer: C
For opposite collinear directions, the resultant magnitude is the difference: 12 − 7 = 5 N.
