Unformatted text preview: Joules, we must have j F j = 100 : 2 p 2 ² 353 : 55 Newtons. 1 Solution 2 (the easy way): Recall that the magnitude of the torque is j & j = j r jj F j sin ( ± ) where r is the &wrench±vector, F is the force vector, and ± is the angle between r and F . In this problem, the wrench vector is r = 0 : 4 i and hence j r j = 0 : 4 . Also ± = 135 & . Therefore j & j = 0 : 4 j F j sin (135 & ) or j & j = 0 : 2 p 2 j F j . In order to have j & j = 100 Joules, we must have j F j = 100 : 2 p 2 & 353 : 55 Newtons. 2...
