Jamal and Dayo are lifting a large chest, weighing 207 lb, by using the two rope handles attached to either side. As they lift and hold it up so that it is motionless, each handle makes a different angle with respect to the vertical side of the chest (Fig. P5.76). If the angle between Jamals handle and the vertical side is 25.0 and the angle between Dayos handle and the vertical side of the chest is 30.0, what are the tensions in each handle? FIGURE P5.76

A uniform plank of length 2.00 m and mass 29.5 kg is supported by three ropes, as indicated by the blue vectors in the figure below. Find the tension in each rope when a 685–N person is d = 0.500 m from the left end. magnitude of T1 = magnitude of T2 = magnitude of T3 =
When a 100 N bag of nails hangs motionless from a single vertical strand of rope, how many newtons of tension are exerted in the strand? What if the bag is supported by four vertical strands?
A mountain climber practices his technique in a mountain climbing school by balancing while suspended by two ropes attached to the ceiling. As shown by the figure, the left rope makes an angle of 60 degrees with the horizontal ceiling and the right rope makes an angle of 30 degrees with the horizontal ceiling. If the right rope has tension T1=322 N, what is the weight of the mountain climber?
A 75-kg petty thief wants to escape from a third-story jail window. Unfortunately, a makeshift rope made of sheets tied together can support a mass of only 58 kg. How might the thief use this “rope” to escape? Give a quantitative answer.
The figure shows an object of mass ?1 = 1.0 kg on an inclined frictionless surface. The angle of theinclined surface is ? = 25 with respect to the horizontal. The object of mass ?1 is connected by anideal string over an ideal pulley to a second object of mass ?2 = 2.05 kg on a horizontal frictionlesssurface below the overhang that is formed by the inclined surface. Furthermore, an external force ofmagnitude ???? = 10 N is exerted on the object with a mass ?1. We observe both objects accelerate. i. Draw separate free-body diagrams of all the forces acting on the two objects ii. Calculate the tension in the string connecting the two objects.
