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

The long side of the rectangle is twice as long as the short side. An axis of ro- tation is shown perpendicular to the plane of the rectangle at its center. A third force (not shown in the drawing) is applied to cor- ner A, directed along the short side of the rectangle (either toward B or away from B), such that the piece of wood is at equilib- rium.

Problem The coefficient of friction between blocks is us = 0.4, at what angle will the block start sliding if it is initially at rest? Solution Let us obtain the net force in the axis perpendicular to the inclined plane. By virtue of the first law of motion (equilibrium), the net force is 2 F perpendicular =n- Fgperpendicular Thus, the normal force is n= m cos On the axis parallel to the inclined, the net force is Z FI - Fg||-fs,max= Substituting the forces, we get the following: mg smg By simplifying, we get the following: tan(theta) = mus Thus, the angle that the object will slide is: (rounded of to the ones)

Estimate the nett force if cach muscle has a diameter of about 5.0 mm and exerts a force in a direction of 25° from the vertical. (Use a force per unit area of muscle of 7x10° N/m²). An 18 kg penguin slides down an iceberg at an angle of 15° to the horizontal. Friction between the penguin's body and the ice surface is negligible. Determine the normal force acting on the penguin and its acceleration down the iceberg. A manufacturer of children's slides does some tests and discovers that the slope of a slippery slide must be at least 25° to the horizontal for the slide to work. The child involved in doing the testing weighs 35 kg. What is the coefficient of static friction between the child and the slide? A car drives onto a section of the road which is covered in ice.
