Neither of them drew afree body diagram (FBD), even though they always drew FBDs on problem-solving questionsthey encountered on their midterm and final exams. For parts A and B, they simply observed thattension from the string creates

and the object subjected to the general rigid bodymotion and the deformation is presented in fig.2. Consider a point P in the non-deformedoriginal body translated to point p through rigid-body translation ⃗ . Due to the additional rigidbody rotation and deformation, the target point Q displaced to point q. Subsequently, the smallelement vector changed to .The position vectors of point Q and q are given by ⃗ (5)and ⃗ ⃗ ( ⃗) . (6)By comparing the position vector ⃗ and , the small element
