simple trig problem.
485/tan(72.8) = 150.13 N
then sqrt(150.13^2 + 485^2) = magnitude of the vector = 507.7 N
confident draw the vector and make a triangle out of it. you be attentive to the perspective and y factor. employing trig (ie sin(theta)=opposite/hypotenuse, cos(theta)=adjacent/hypotenuse) locate the cost of the hypotenuse, that could desire to be the stress vector. Then employing the equations above sparkling up for the x factor.
