Vector Mechanics For Engineers Statics 12th Edition Solutions <2025>

Rx = F1x + F2x = 86.60 + 75 = 161.60 N Ry = F1y + F2y = 50 + 129.90 = 179.90 N

Let's take a look at some key problems and their solutions in the 12th edition: Rx = F1x + F2x = 86

rOA = 2i + 3j + 4k

Find the resultant force components.

R = √(Rx^2 + Ry^2) = √(161.60^2 + 179.90^2) = 243.30 N θ = tan^(-1)(Ry/Rx) = tan^(-1)(179.90/161.60) = 48.19° Fy = 0

Assuming Fx = 200 N, Fy = 0, Fz = 0 (since the force is acting in the x-direction) Rx = F1x + F2x = 86

Calculate the moment of the force about point O.
