... In what ways do you think fluid exerts stress on the object submerged in it? Fluid cannot exert shearing or tensile stress. Thus, the only force the fluid exerts on an object immersed in it is the force perpendicular to the surface of the object. This force by the fluid on an object usually is expre ...

... light spring is attached to the more massive block, and the blocks are pushed together with the spring between them (Fig. P9.11). A cord initially holding the blocks together is burned; after that happens, the block of mass 3m moves to the right with a speed of 2.00 m/s. (a) What is the velocity of ...

... Derived Units Some physical quantities are so widely used that their units have special names. They are called derived units because they are defined in terms of the base SI units. The SI unit of force is the Newton (N). Let us see how it is constructed in terms of base units. Force is defined by: ...

... A simple clutch consists of two cylindrical plates that can be pressed together to connect two sections of an axle, as needed, in a piece of machinery. The two plates have masses MA = 6.0 kg and MB = 9.0 kg, with equal radii R0 = 0.60 m. They are initially separated. Plate MA is accelerated from res ...
