Hey all!
I just found out and joined the forum. I am a Biomedical Engineering student and in desperate need of help. We were given couple of questions to hand in next week. I managed to solve most of them, but I'm kinda lost at these 3 questions.
For question 2.1, I managed to calculate the values for a/b/c. But I couldn't find the mechanical energy to be invested in order to sustain the movement in these conditions.
Question 2.1: http://s24.postimg.org/ug6ccd8h1/Scan3.jpg
Solution I tried: http://s23.postimg.org/gec2oihgb/q2_1_sol.jpg

Question 4.2, the model given meets the standard formula for joint moment/reaction force calculations except one point. The object in hand. I could get this to the point of calculating by putting the angular acceleration, mass of forehand and mass of object in classical formula, but I'm not sure if that is the right way of solving the question.

Question 4.1 is where I am all lost. I know that moment of inertia is to be calculated considering the centre of mass of leg but the movement and lengths of y1 and y2, and calculating them related to centre of mass of leg is a mystery to me. I couldn't even have a try on this one.
Question 4.1: http://s11.postimg.org/ab1weck37/Scan2.jpg
No Solution
Related material: Nothing :(
I know I may be asking too much. But I'm honestly caught in the middle, I checked every resource I came up on internet but couldn't make much out of them. I would be extremely glad if you could help me on those.
Thanks in advance!
