Question

if young modulus and bulk modulus for Silver bi 7.25 into 10 to the power 11 dyne per CM square and 11 into 10 to the power 11 dyne per CM square respectively find the poisons ratio for silver ​

Answer 1

Answer:

Two permanent magnets,

Explanation:

An electric motor is composed of the following: - Two permanent magnets, which form the stationary part of the motor, known as the stator. - A commutator is a split ring which changes the polarity of the electromagnets, known as the rotor coils. - Brushes that conduct a current from the power sources to the commutator.

Answer 2

Answer:

u = 0.39

Explanation:

E = 3K(1-2u)

$1- 2u = \frac{E}{3K}$

$2u = 1 - \frac{E}{3K}$

$u = \frac{1}{2} (1 - \frac{E}{3K} )\\u = \frac{1}{2} (1 - \frac{7.25 * 10^{11} }{3*11*10^{11}} )\\u = \frac{1}{2} (1 - 0.219 )\\u = 0.39$
