Answer:
240.4 Nm
Explanation:
The torque is the cross product of the force vector and the moment arm length vector
[tex]T = \vec{F} \times \vec{s}[/tex]
[tex]T = Fs sin\theta [/tex]
[tex]T = 16*(25.5 + 7 + 22)* sin16^o [/tex]
[tex]T = 872*0.276[/tex]
[tex]T = 240.4 Nm[/tex]
The magnitude of the torque about the elbow produced by the weight is 240.4 Nm.
Since there is an angle θ= 16.0° below the horizon and a 16.0 N weight is placed in the hand. The shoulder-to-elbow length is 25.5 cm and the an elbow-to-wrist length is 22.0 cm. The center of the weight is 7.0 cm
So, here the magnitude should be
= 16 * (25.5 + 7 + 22) * sin 16 degrees
= 872* 0.276
= 240.4Nm
