Trina is a gym goer with a leg length of 84 cm. Suppose that she is in the gym doing straight leg raising with 10 lb weights. Compute for the force that the muscle should exert in order to (1) maintain it in the position and (2) lift the weight up given that the distance of the effort (muscle) from the joint is 54 cm, distance of the weight is 80 cm, and the COM is 45 cm from the joint.   ANSWER THESE QUESTIONS: 1.) Compute for the force that will maintain the position. 2.) Compute for the force needed to lift the weight higher. 3.) Assuming that the hip flexion angle is at 60 degrees, compute for the linear displacement of the leg.

Question

Trina is a gym goer with a leg length of 84 cm. Suppose that she is in the gym doing straight leg
raising with 10 lb weights.

Compute for the force that the muscle should exert in order to (1) maintain it in the position and
(2) lift the weight up given that the distance of the effort (muscle) from the joint is 54 cm,
distance of the weight is 80 cm, and the COM is 45 cm from the joint.

 

ANSWER THESE QUESTIONS:

1.) Compute for the force that will maintain the position.

2.) Compute for the force needed to lift the weight higher.

3.) Assuming that the hip flexion angle is at 60 degrees, compute for the linear
displacement of the leg.
