5.6 A 7.5 cm diameter jet of water is directed at a hole in a vertically supported plate Some of the water spreads as a film over the surface of the plate and the remainder leaves horizontally through the hole. The angle between the jet and the plate is 65° and the velocity within the jet is uniform and 10 m/s. Assume inviscid flow and neglect gravity forces. The density of water is 1000 kg/m a) What is the velocity...

Objective To determine the force generated by a jet of water striking on a surface Description of apparatus The supply is led to a vertical pipe terminating in a tapered nozzle. This produces a jet of water which impinges on the vane in the form of a Flat Plate, Hemispherical Cup, Conical Plate or 30° Angled Plate. The nozzle and vane are contained within a transparent cylinder; at the base of the cylinder there is an outlet by which the...

A triangular plate of narrow rectangular cross-section and uniform thickness is loaded uniformly along its top edge as shown in the following figure. Verify that the Airy stress function º = zip.cotoo | - tan a + xy + (x2 + y2)(a - tan-+ %) solves this plane problem. For the particular case of a = 10°, explicitly calculate the normal and shear stress distribution over a typical cross-section AB. We were unable to transcribe this image

Please work out 3 clearly and with units. Thanks!
1. A 10-g bullet travels vertically upwards at 1000 m/s, then strikes and passes through a 2.0-kg block initially at rest. The bullet emerges from the block with a speed of 400 m/s because it transfers momentum to the block. (a) How much momentum did the block gain? (b) How fast is the block now moving, and what is its kinetic energy? (c) Using energy considerations only, to what maximum height...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
