The board sandwiched between two other boards in Figure P5.97 weighs 95.5 N. If the coefficient of static friction between the boards is 0.663, what must be the magnitude of the compression forces (assumed horizontal) acting on both sides of the center board to keep it from slipping?
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
4. You have been tasked with retrieving a crate from a 4-m long beam that is suspended by two cables, as shown. While standing 1.5 m from the left edge of the beam, you silently hope that the cables are strong enough to hold the weight of the beam, the box, and you! The masses of the beam and you are 10 kg and 70 kg, respectively. The cables are rated for a tension of 1000 N. Do the cables hold? In other words, what is the tension in each cable? Hint: you can assume the box is sitting on the very end of the beam. 30° 20° 4.0 m
