coplaner And Concurrent

Question 1

coplAnar

Answer 1

If all the forces in a system
lie in a single plane, it is called a coplanar force system.

Question 2

Concurrent

Answer 2

If the line of action of all the forces in a system
passes through a single point, it is called a concurrent force system

Question 3

Collinear

Answer 3

If the line of action of all the forces lies along a single line then it is called a
collinear force system.

Question 4

coplAnar parallel force

Answer 4

All forces are parallel to each other and lie in a single plane.

Question 6

coplAnar concurrent forces

Answer 6

straight.

Question 7

Collinear forces

Answer 7
