This is the last question I will as for help on for this assignment I am doing I promise. For all you out there who know Physics you are awesome, cause boy is this stuff hard. Here is the question I am have trouble with now, again this could be an easy question but I am not sure on what to do. I have been trying to figure it out but no way can I do it.
A student is trying to life a weight held in the hand. The distance from the elbow joint to the centre of gravity of the weight they are trying to life is 30cm. Their flexor muscles of the forearm insert 5cm from the centre of rotation of the elbow joint (the pivot). If the tendon inserts into the bone at an angle of 20 degrees, and the muscle is able to generate 40 kilograms of internal tension; How much weight could the student lift??
I hate to be bothering for help but this assignment I am doing is worth 20% and I am hoping to do well, the rest of teh questions on this part I think I can handle. If someone could help me with this one it would be great.
Thanks,Woody
