Slide #1: This slide is just an introduction to the whole assignment

Slide #2 Please do the following:

- Using the ratio of lever arm distance for balanced torque, ESTIMATE the force of her QUAD muscles, relative to the bar force. DRAW the length of the muscle vector accordingly.

Slide #3 Please do the following:

I

-CHOOSE a bodyweight ratio from the giving chart

-How much force she pushes against, with both legs, in terms of body weight. ASSUME this is the force that the person is pushing against in the picture on the previous page/slide (SLIDE #2)?
Choose a bodyweight ratio

How much force she pushes against, with both legs, in terms of body weight. Assume this is the force that the person is pushing against in the picture on the previous page

Fbar both legs

? Wbody

Fbar one leg

~? Wbody

From the information on the previous page,

Determine how much force the quad muscle will exert doing this. This will also be the force on her patellar tendon.

In terms of body weight
Fquad/patellar= 9 (?Wbody)
Assume the person weighs 500N
In Newtons Fquad/patellar = ? N
