If a force of vecF=-3veci+vecj+5veck act...

If a force of `vecF=-3veci+vecj+5veck` acts at a point `vecr=7veci+3vecj+veck`, then calculate the torque produced by the force.

Text Solution

Verified by Experts

Torque=`vectau=vecrxxvecF`=
`=hati(16-1)-hatj(35-(-3))+hatk(7-(9))=hati(14)-hatj(38)+hatk(16)`
`:." "vectau=14hati-38hatj+16hatk`
Magnitude of torque=`sqrt(14^2+38^2+16^2)=sqrt(196+1444+256)=sqrt(1896)=43.54Nm`
