Question 4 A homogeneous slender rod AB of mass m and length L is held in the position shown in Figure Q4. The end A of the rod is free to move along the smooth horizontal surface. The end B of the rod is connected to rod BC of negligible mass. The rod AB is released from rest in the position shown when 0 = 60°. If the acceleration of end B is ā, = -a,j, derive the expressions in...
a ng mass is being held up by a string which is connected to two other strings as shown in the figure below. What is the tension in all three strings? 4) A uniform horizontal bar of length L = 5.0 m and weight 140 N is pinned to a vertical wall and
A woman with mass m is standing on a platform and holding onto a light rope attached to a hook in the ceiling. A second rope, also attached to the hook, is being held by a man with larger mass M on a second platform. The ropes are the same length, and the ropes are initially horizontal. The two people start from rest and swing toward each other. They meet at the lowest point of their swings, and grab onto...
A uniform plank of mass 30kg and length 20m is supported by two ropes T1 and T2 attached as shown on the diagram. Two masses 20kg and 25kg are suspended are shown to keep the plank in equilibrium. Find the tension T1 and T2 due to the two ropes. I'm having trouble with this question. Would love to see the actual work, so I can understand the concept. 4. A uniform plank of mass 30 kg and length 20 m,...
d-f Reasoning Problem 2. (28 pts) A uniform 35.0-kg aluminum platform of length 5.0 m is supported b two light cables, as shown below. An 7o.o-kg painter stands o.8 m from the left end of the scaffold, and his painting equipment is 1.o m from the right end. If the tension in the left cable is twice that in the right cable, find: d. the tensions in the cables (10 pts) e. the mass of the equipment.(10 pts) f. How...
A woman with mass m is standing on a platform and holding onto a light rope attached to a hook in the ceiling. A second rope, also attached to the hook, is being held by a man with larger mass M on a second platform. The ropes are the same length, and the ropes are initially horizontal. The two people start from rest and swing toward each other. They meet at the lowest point of their swings, and grab onto...
A uniform beam resting on two pivots has a length L=6.00m and mass M =88.9kg. One pivot supports the left end of the beam and the second pivot is placed at distance ℓ=4.00m away from it. A woman of mass m=57.3KG steps onto the left end of the beam and begins walking to the right as in the figure below. Find the position x of the woman when the beam is about to tip. Define the origin (x=0) as the...
A uniform beam of mass my and length L hinged on the right supports a worker of mass my at a distance d' from its right end. A rope attaches to the left end of the beam at an angle . a) [5 pts) Reproduce this sketch and show all relevant forces acting on the beam. (You may simplify the drawing of the man - a stick figure will do, or a box.) b) [12 pts) Write the three equilibrium...
1. (10 pts) A uniform 30.0-kg scaffold of length 3.0 m is supported by two light cables, as shown in the figure. A painter A of mass "m" kg stands 0.5 m from the left end of the scaffold. If the tension in the left cable cable is twice that in the right cable, find the tensions in the cables and the mass of the painter A. (Answer the following questions to solve this problem) a. (2 pts) Draw the...
A uniform plank of mass 5.00 kg and length 3.60 m is supported by vertical ropes at its ends as in the figure below. A 60.0-kg painter is located 0.500 m to the left of the center and an 8.00 kg bucket is 1.00 m to the right of the center. Find the tensions ?1 and ?2 in the ropes.
