Answer:
D) D = , E) (C, D) = (
Explanation:
Part D) two expressions are indicated
3C + 4D = 5
2C +5 D = 2
let's simplify each expression
3C + 4D = 5
4D = 5 - 3C
we divide by 4
D =
The other expression
2C +5 D = 2
2C = 2 - 5D
C =
we can see that the correct result is 1
Part E.
It is asked to solve the problem by the substitution method, we already have
D =
we substitute in the other equation
2C +5 D = 2
2C +5 (5/4 - ¾ C) = 2
we solve
C (2 - 15/4) + 25/4 = 2
-7 / 4 C = 2 - 25/4
-7 / 4 C = -17/4
7C = 17
C =
now we calculate D
D =
D = 5/4 - 51/28
D =
D = - 16/28
D =
the result is (C, D) = ( )
The strain in the rod is
Given:
Young's modulus, Y =
Steel density,
Length of the rod, L = 80 cm = 0.800m
The speed of the wave in the rod is,
Hence the time taken by the wave to travel the end of the rod is,
The velocity of the rod is,
The other end will keep moving after the front end hits the wall until the wave reaches the other end, given the period determined by the above problem.
As a result, before the wave reaches the end of the rod, it has traveled a distance of
The strain in the rod is given by,
Hence, the strain in the rod is .
In terms of physics, strain is defined as the fractional modification of configuration.
A system's reaction to an applied stress is called a strain, according to 2. A force that loads a material results in a stress that leads to deformation. Formula for a strain
Change in configuration equals strain first arrangement
It is a dimensionless quantity that lacks a unit.
Change in object size / original object size is known as strain.
It is a quantity without units or dimensions.
Strain kind.
Object length change divided by starting object length equals longitudinal strain.
L/L stands for longitudinal strain.
Change in object volume divided by starting object volume equals longitudinal strain
