T=rF

The Attempt at a Solution

I'm not sure at all how to solve this problem. If anyone can help me out with setting this up and proceeding from there that would be a big help.

 

[jbaratta]

start with a free body diagram of the lower arm showing all forces and reactions, then balance forces and moments

 

[VitaX]

Is that free body diagram correct and what would the force be on F4? And is my method for part a and b correct?

 

[VitaX]

Anyone know if the above is right?

I can provide some insight into the forces acting on a Bowler's arm. First, we must understand that a Bowler's arm is subject to both external and internal forces. External forces include the weight of the arm itself, as well as the weight of the bowling ball being held in the hand. These forces act downwards towards the ground, and can be represented by the equation T = mg, where T is the tension in the arm, m is the mass of the arm and ball, and g is the acceleration due to gravity.

Internal forces, on the other hand, are generated by the muscles and tendons in the arm. These forces are responsible for the movement and control of the arm during the bowling motion. These forces can be represented by the equation T = rF, where T is the tension in the arm, r is the radius of rotation, and F is the force generated by the muscles and tendons.

In order to successfully bowl, the Bowler's arm must be able to overcome the external and internal forces acting on it. This requires a balance of strength, control, and technique. Additionally, factors such as the weight and grip of the bowling ball, as well as the speed and angle of the arm swing, can also affect the forces acting on the arm.

In conclusion, the forces acting on a Bowler's arm are complex and require a combination of physical and technical skills to overcome. By understanding these forces and how they interact, a Bowler can improve their performance and achieve success in the sport.
