Draw a free body diagram of an individual performing calfraises, rising onto the balls of their feet and then lowering theirheels.

Draw a free body diagram of an individual performing overheadtriceps extensions with a 5kg dumbbell.

Draw a free body diagram of the scenario described below usingthe provided: A gym-goer is holding a dumbbell statically while hesnaps a quick selfie in the mirror. Here is what you know:

• Elbow flexion angle = 90 ?
• The torque generated at the elbow due to the force of thebiceps = 78.48Nm
• External resistance = 20kg
• Moment arm of the biceps = 2cm
  • Distance from the elbow joint center to the external resistance= 40cm

Determine which of the followingcorrectly describes the mechanical advantage of the thirdsystem?

• Mechanical advantage is greater than 1.0 and therefore a lowforce is needed to overcome the resistance.
• Mechanical advantage is less than 1.0 and therefore a highforce is needed to overcome resistance.
• Mechanical advantage is greater than 1.0 and therefore a lowforce is needed to overcome resistance.
• Mechanical advantage is less than 1.0 and therefore a low forceis needed to overcome resistance.
