Mechanical Equilibrium Problems Apair of students are lifting a heavy trunk on move-in day (Figure 1) Using two ropes tied to a small ring at the center of the top of the trunk, they pull the trunk straight up at a constant velocity R. Each rope makes an angle with respect to the vertical. The gravitational force acting on the trunk has magnitude Figure 1 previous l 5 of 12 l next You completed this assignment. The trunk is moving at a constant velocity. This means that you can model it as a particle in dynamic equilibrium. Furthermore, you can ignore the masses of the ropes and the ring because it is reasonable to assume that their combined weight is much less than the weight of the trunk. Part A The most convenient coordinate system for this problemis one in which the yaxis is vertical and the ropes both lie in the xy plane, as shown below. identify the forces acting on the trunk, and then draw a free-body diagram of the trunk in the diagram below. The black dot represents the trunk as it is lifted by the students Draw the vectors starting at the black dot. The location and orientation of the vectors will be graded. The length of the vectors will not be graded. Xdoloto element help Rope 2 Rope 1 My Answers Give Up Submit All attempts used; correct answer displayedExplanation / Answer
a] The drawing is correct. Try to draw T1 and T2 smaller so that their vertical components cancel Fg.
d]When the angle is more T increases, when it is less T decreases, when unchanged T remains same.
