Question

write classification of force' system and explain any one in detail​

Answer 1

There are two main types of force systems.

Co-planar and non-co-planar

Explanation:

• There are two main types of force systems.
• Coplanar and non-coplanar
• The examples of coplanar force systems are concurrent, parallel, and linear as well as non-concurrent and non-parallel.
• The sample of non-coplanar force systems is concurrent parallel and non-concurrent and in-parallel.
• Co-planar forces are those which lie on the same plane and non-coplanar are those which do not lie on the same plane.

Answer 2

The forces are classified as contact force and non-contact force.  

Explanation:

• The forces are classified as contact force and non-contact force.  
• The non-contact forces are those which can not be seen or touched such as gravitational force, nuclear force and electromagnetic force, etc.
• The contact forces are those which result from the physical contact such as pushing of cart or door.
• These can be co-planar and non-coplanar also.
• Which lie on the same plane are co-planar and vice versa.
