The walker family is building a cabin for vacationing. mr. walker and his son terrell have erected a scaffold to stand on while they build the walls of the cabin. as they stand on the scaffold terrell pulls on a rope attached to a support beam with a force of 400 newtons (n) at an angle of 65 with the horizontal. mr. walker pulls with a force of 600 newtons at an angle of 110 with the horizontal. what is the magnitude of the combined force they exert on the log?

Alright, lets get started.

Please refer the attached diagram.

400N is applied with angle 65 degrees.

So, there will be two components of the force.

X component will be = fx1 = 400 cos 65

X component will be  fx1 = N

Y component will be fy1 = 400 sin 65

Y component will be fy1 =

Similarly, 600 N force is applied on angle 110degrees, so the components will be

X component fx2 = -600 cos 80

X component fx2 = -

Y component fy2 = 600 sin 80

Y component fy2 =

So, combined X component will be =  

Combined Y component will be =

So, magnitude will be  =

So the magnitud of combined force will be 955.58 N.  :   Answer

Hope it will help :)
