Math Problem Statement
what is the resultant
Solution
To find the resultant force from the given diagram, we need to calculate the sum of all forces in both the - and -directions. Let’s break down the forces step by step.
Given Information:
- at an angle of from the negative -axis
- along the positive -axis
- along the negative -axis
- along the negative -axis
Breaking down the forces into components:
Force :
- makes a angle with the negative -axis.
Force :
- is along the positive -axis.
Force :
- is along the negative -axis.
Force :
- is along the negative -axis.
Summing up the components:
Sum of -components:
Sum of -components:
Now, let's calculate these values and find the magnitude of the resultant force and its direction.### Results:
- Sum of -components:
- Sum of -components:
- Resultant force:
- Direction of the resultant: (from the positive -axis)
The resultant force has a magnitude of 11.3832 lbf and is directed at an angle of 74.72° from the positive -axis.

Sum of forces in x-direction: ΣFx = F1x + F2x + F3x + F4x
Sum of forces in y-direction: ΣFy = F1y + F2y + F3y + F4y
Resultant force: FR = sqrt((ΣFx)^2 + (ΣFy)^2)
Angle of resultant: θ = atan(ΣFy / ΣFx)
