Calculate the resultant of this system of forces Enter your

Calculate the resultant of this system of forces. Enter your answer with 3 significant figures for the magnitude and angle of the resultant vector. You do NOT need to enter (+) or (-) in the answer fields.

Solution

F1 --25lb at angle of 60deg

F2 ---- 45 lb at an angle of 10deg

X axis component -- 25cos60 +45cos10 = 56.816 lb

Y component --25siin60 + 45sin10 = 29.465 lb

Resultant = sqrt(X^2 +Y^2) = 64 lb

Angle = tan^-1( 29.465/56.816) = 27.41 deg
