To obtain the resultants what method is used?
Expert Solution

Step 1
The resultant force of concurrent forces can be calculated by various methods. Some of the methods are given as,
(1)
Parallelogram Law:
This law is used when two concurrent forces make an acute angle. This law is used to calculate the resultant when only two forces will be in a system.
If two forces P and Q are acted at an acute angle then the resultant force, R is written as,
(2)
Sine Rule:
This law is used when two concurrent forces make any angle. This law is used to calculate the resultant when only two forces will be in a system.
The diagram of the concurrent forces is given as,
The expression of Sine rule is given as,
