Question
Transcribed Image Text:Your biceps connect your shoulder to your forearm. They are connected offset from your elbow
so that when you bend your arm, your biceps apply a torque to rotate your forearm.
Estimate the force required by your biceps to do a bicep curl (a type of weightlifting).
Remember to include the weight of your arm and the weight itself, each applying their torques
at the proper locations.
Additional Questions
1. How much more weight could you lift with the same bicep force if your biceps attached at
the midpoint of your forearm? At the wrist?

- Prof. de Silva conducted the experiment in terms of physics principles related to rotational motion. The experiment involved Prof. de Silva using a sword to break a long wooden stick that is balanced on two wine glasses. 1. Describe Rotational Force. 2. Provide a diagram showing all the forces acting in the above scenario and their direction of those forces. 3. Your opinion on the performance and apply physics principles to explain the outcome and any limitations.arrow_forward1. Calculate the torque about the z-axis pointing out of the page at the origin in the following figure given that F₁ = 2 N, F₂=9N, F3=4 N, F₁=5 N. Hint: Use the sign convention for torques, counter-clockwise rotation corresponds to a torque in the positive z-direction and clockwise rotation corresponds to a torque in the negative z-direction. Which forces produce clockwise rotations and which forces produce counter-clockwise rotations? While using the formula for cross-product AXB=ABsine, remember that is the angle between the tails of the vectors A and B. To determine e rearrange the vectors so that their tails coincide.
