Athletes sometimes do an exercise called "curing weights." This exercise consists of holding the arm from the shoulder to the elbow steady and snug against the body while pulling a weight to the chest. Calculate the torque about the elbow caused by a 40 pound weight that makes an angle of 55 degrees with respect to the body.(adsbygoogle = window.adsbygoogle || []).push({});

i know the formula is torque= F s sin()

I found the force by coverting pound 40pounds/2.2046kg= 18.144kg x 1000g= 18144 g x 9.81m/s =177993force

torque= F s sin(55)= (18144g)(9.81 m/s2) (s) sin(55)=

but what is s they don't give me the s. do i have to use other formula? am confused? please help
