1. Calculate the buoyant force F, necessary to completely submerge a beach ball r = 48.1...
3. Suppose you have a rock with a mass of 305 g. When attached to a spring scale and lowered completely into water the spring scale reads Fe 2.10 N. Note that this reading is significantly lower than the rock's weight Fo Mg (3 N), because of the buoyant force helping to support it. From this information, calculate the following: (a) Fe: the magnitude of the buoyant force exerted on the rock. Use N2L in conjunction with the FBD shown...
Exercise 11 A squarish object is suspended from the end of a long, uniform bar tilted at an angle 0 above the horizontal. The bar's lower end is anchored to a wall, and the upper end is attached to a horizontal cable anchored to the same wall. All parts of this system are in equilibrium. cable wall object (a) Create a complete FBD for the bar. The FBD should not show the hanging object, the wall, or the cable, just...
