Since I train powerlifting I have started to get interested in the mechanical analysis of the different exercises. But the bench press I haven't been able to figure out. When I am considering a dumbbell bench press the mechanics seems simple, but when I consider a barbell bench press it becomes...

Homework Statement Please help, anyone. This is not homework as such but rather it is for test preparation. The biomechanics problem with diagrams is here: http://oregonstate.edu/instruct/exss323/Xtra_Problem4.pdf" As you will note, the answers are already provided. I am only interested in...

Say I want to specialize in biomechanics in biomedical engineering. Should I go strait to a undergraduate biomedical engineering program or a mechanical engineering program and then specialize?

Homework Statement Homework Equations Fm= (Fn*Rw)/Rm The Attempt at a Solution honestly i have no idea where to even start for this, the equation i gave is probably way off but as i said, i have no idea.

[b]1. you and your partner are astronauts wearing 10kg space suits, you are drifting away from the spaceship 0.1m/s and your partner is stationary directly between you and the spaceship which is 100m away from your partner. The ship cannot move and no ones aboard to get you. You are fine but...

The title says all.

Homework Statement A person with a mass of 80kg pulls horizontally on the handle of a door which is locked. At that instant, the ground reaction force has a magnitude of 810N. What is the force applied to the door? (200 N) Homework Equations The Attempt at a Solution It seems...

Homework Statement 1. A child sits in a sled on a horizontal snowy surface. The combined mass of the child and the sled is 30 kg. The static coefficient of friction is 0.2 and a kinetic coefficient of friction of 0.15. How much force does it take to initiate movement of the sled? (59 N) 2...

Hey guys, I'm having a lot of trouble trying to work out this problem and don't know exactly where to start. I was wondering if someone knows how to tackle this? A unipennate muscle of pennation angle 150 inserts into the distal bone of a hinge joint at an angle of 300. If the tension in...

urgent help for biomechanics question the question that I am not sure of is: A body of mass 9.4 kg initially moving in a straight line at 3.7 m/s is acted on by an accelerating force of 36.5 N (in the same direction as initial motion) for 1.32 seconds Calculate the velocity of the body at the...

Hi everyone...I am in my last semester of college and physics has returned to my life.. It has been approximately 3 yrs since physics and 6 years since calculus so I am really rusty regarding classical physics (mechanics). here is my problem Listed below are three vectors that point from...

Hi, I'm a mechatronics and robotics student. What is the purpuse of studying biomechanics? Is for humanoid robots or for prosthetics? If for prosthetics why doing it a a college who is not of bioengineering or of medicine?

Homework Statement A collision occurs between two football players. Player 1 has mass of 75 kg and a velocity of 6 m/s. Player 2 has mass of 150 kg and a velocity of -3 m/s (meaning going in an opposite direction). Assuming an ELASTIC collision, what is the final velocity of player 2...

Homework Statement A tendon starts off with an initial length of 10 cm and a cross-sectional area of 0.1 cm^2. A force of 100 N is applied, which stretches the ligament to a new length of 11 cm. What is the Modulus of Elasticity (E) for this ligament (in MPa)? Homework Equations Stress...
