Two plates of thicknesses 25mm and 15mm are clamped together by an M8x1.25 bolt used with a regular nut and with regular washers placed on both the nut and bolt head sides. The top plate is 25mm thick with E=70 GPa and the bottom plate is 15mm thick with E=90 GPa Determine the fraction of external load borne by the bolts. The bolt, nut and washer are made up of steel (E=207 GPa). Note: Round up the bolt length to the nearest 5mm

Two parallel conducting plates are oriented in an ? − ? coordinate system. The plates are separated by a distance ? = 0.05 ?, and the origin of the coordinate system is halfway between the plates. The plate separation is very small compared to the size of the plates. The left plate is at a potential ?L = 50 ?, and the right plate is at a potential ?R = 10 ?. 1. A proton at the origin begins at...

Consider the steady flow between two flat plates. The plates are 10 cm apart and the width of the channel is 10 cm. Water is the working fluid. The flow velocity varies linearly from zero at the bottom plate to 10 m/s at the top plate. (This general class of flows is known as Couette Flow). Determine the total mass flow and momentum per unit time crossing an imaginary plane across the channel.

A wrench is used to apply a torque to a bolt. Forces F, through Fall have the same magnitude. The point of application of force F, and F) is a distance d from the center of rotation of the bolt. The application points of F). F, and F3 are all distance d apart, as shown. Use the convention that counter-clockwise torques are positive; clockwise torques are negative. Part (a) Which of the labeled forces will apply the largest magnitude torque on...

Two flat plates of glass with parallel faces are on a table, one plate on the other. Each plate is 11.0 cm long and has a refrac- tive index of 1.55. A very thin sheet of metal foil is inserted under the end of the upper plate to raise it slightly at that end, in a man- ner similar to that discussed in Example 35.4. When you view the glass plates from above with reflected white light, you observe that,...
