Question
Chapter 6, Problem 1CQ
To determine
Whether the total work done by the external forces on an object moving in a circle is necessarily zero or not.
Expert Solution & Answer
Answer to Problem 1CQ
The total work done by the external forces on an object moving in a circle is not necessarily zero.
Explanation of Solution
According to the work energy theorem, the work done on an object is equal to the change in kinetic energy of the object in the process. The work energy theorem can be applied to the objects in circular motion to find whether the work done on the objects undergoing circular motion is zero or not.
If the object under the circular motion is assumed to be as appoint particle, the total work done on it by external forces is equal to the change in its kinetic energy. There is a possibility for the object moving in a circle to change its speed as it goes around. The change in speed can cause a non-zero value for the change in kinetic energy of the object. Hence, the total work done on the object in circular motion is not necessarily zero.

Can someone help me
Need help on the following questions on biomechanics. (Please refer to images below)A gymnast weighing 68 kg attempts a handstand using only one arm. He plants his handat an angle resulting in the reaction force shown.A) Find the resultant force (acting on the Center of Mass)B) Find the resultant moment (acting on the Center of Mass)C) Draw the resultant force and moment about the center of mass on the figure below. Will the gymnast rotate, translate, or both? And in which direction?
Please help me on the following question (Please refer to image below)An Olympic lifter (m = 103kg) is holding a lift with a mass of 350 kg. The barexerts a purely vertical force that is equally distributed between both hands. Each arm has amass of 9 kg, are 0.8m long and form a 40° angle with the horizontal. The CoM for each armis 0.5 m from hand. Assuming the lifter is facing us in the diagram below, his right deltoidinserts 14cm from the shoulder at an angle of 13° counter-clockwise from the humerus.A) You are interested in calculating the force in the right deltoid. Draw a free body diagramof the right arm including the external forces, joint reaction forces, a coordinate system andstate your assumptions.B) Find the force exerted by the right deltoidC) Find the shoulder joint contact force. Report your answer using the magnitude and directionof the shoulder force vector.
