Question

Question 7 10 pts Carter is performing a barbell curl (free weight) with a mass of 18kg. The length of their forearm from the elbow joint to the center of the bar is 0.19m. How much more torque (Nm) is required when the forearm is horizontal compared with when it is at an angle of 34 to the horizon? Note this question is asking for the change in torque from one arm angle to another. Give your answer to one decimal point. 0.6

Step 1

To calculate the torque, we need to multiply the force applied by the distance from the pivot point (elbow joint) to the center of the bar. Given: Mass of the barbell (m) = 18 kg Length of the forearm (L) = 0.19 m The force applied is equal to the weight of the Show more…
