Question

A force F=Fx ˆi + Fy ˆj + Fz ˆk acts on a particle located at X= (x, y, z). Given Fx=−88.3N, Fy=7.56N, Fz=60N, x= −3.65m, y=1.67m and z=7.03m,
calculate the three components of the torque vector ~ = xˆi + y ˆj + z ˆk .
First, calculate the x component.
Answer in units of Nm

Answer 1

Tx =Fx•X = (-88.3) •(-3.65) = 322.2 N,
Ty =Fy•Y = (7.56) •(1.67) = 12.63 N,
Tz = Fz•Z = 60•7.03 = 421.8 N
T = 322.2•I +12.63•j + 421.8•k
