The cumulative effect, or the resultant, of two or more forces is obtained by resolving the forces. This is done by addition if the forces act in the same direction through the same point and by subtraction if the forces act in opposite direcitons through the same point. However, if the forces are placed at an angle to one another, they must be resolved into their consituent x and y (and z if necessary) components and then their resultant is calculated.

Answer:

Cumulative effect of two or more force can be found using Vector sum of all forces

Explanation:

Force is a vector quantity and in order to find the resultant of two or more forces we have to use the concept of vector addition

here we know that vector addition rule is given as

[tex]F_{net} = \sqrt{F_1^2 + F_2^2 + 2F_1F_2cos\theta}[/tex]

here we know that

[tex]\theta [/tex] = angle between two forces

so using this equation we can find the cumulative effect of two forces which are inclined at an angle with respect to each other
