Determine The shear and moment diagrams of the following.

Show that the sum of the forces is equal to minus the rate of change of the momentum in the fields, and interpret this result physically.

A point charge q is a distance a > R from the axis of an infinite solenoid (radius R, n turns per unit length, current I). Find the linear momentum and the angular momentum (with respect to the origin) in the fields.

Choose the only B so that for every matrix A

Determine: The shear, moment, and axial force diagrams.

500 g of dry soil was used for a sieve analysis. The masses of soil retained on each sieve are given below:

The worm has right-hand threads and the pressure angle is 20°. The worm wheel is mounted between two bearings A and B. It can be assumed that the bearing A is located at the origin of the co-ordinate system and the bearing B takes complete thrust load.

Prescott (2004) argued that U.S. employees work 50% more than do German, French, and Italian employees because European employees face lower marginal tax rates. Assuming that workers in all four countries have the same tastes toward leisure and goods, must it necessarily be true that U.S. employees work longer hours? Use graphs to illustrate your answer, and explain why it is true or is not true. Does Prescott’s evidence indicate anything about the relative sizes of the substitution and income effects? Why or why not?

The worm has right-hand threads and the pressure angle is 20°. The worm wheel is mounted between two bearings A and B. It can be assumed that the bearing A is located at the origin of the co-ordinate system and the bearing B takes complete thrust load. Determine the reactions at the two bearings.

500 kJ of heat is removed from a constant temperature heat reservoir maintained at 835 K. Heat is received by a system at constant temperature of 720 K. Temperature of the surroundings, the lowest available temperature is 280 K. Determine the net loss of available energy as a result of this irreversible heat transfer.
