Answer:
The type of cam-based equipment design that would most likely accommodate the bench press exercise is B. a cam with the largest radius in the middle of the range of motion.
Step-by-step explanation:
The bench press exercise involves a pushing motion where the lifter starts with the barbell at chest level and extends their arms to lift the weight. Throughout the exercise, the difficulty of the lift varies depending on the angle of the lifter's arms.
By using a cam with the largest radius in the middle of the range of motion, the equipment can provide a mechanical advantage during the most challenging part of the lift, which is when the arms are extended and the lifter is pushing against the resistance. This design allows for a smoother and more controlled motion, distributing the load more evenly and reducing the risk of injury.
On the other hand, if the cam had the largest radius at the beginning or end of the range of motion, it would not provide the necessary assistance during the most challenging part of the lift. This could make the exercise more difficult and potentially increase the risk of strain or injury.
Therefore, a cam with the largest radius in the middle of the range of motion would be the most suitable design for accommodating the bench press exercise.
