<h2>
Diameter of rod = 19 mm</h2>
Step-by-step explanation:
We have the equation for elongation
Here we have
Elongation, ΔL = 0.266 in = 0.00676 m
Length , L = 35 ft = 10.668 m
Load, P = 8000 lb = 35585.77 N
Modulus of elasticity, E = 30,000,000 psi = 2.07 x 10¹¹ N/m²
Substituting
Diameter of rod = 19 mm
Top one is 32.
Second from the top is 8.
Second from the bottom is 12.
Last one is 28.
Hope i helped. Any questions u have ask me.
The answer would be x= 27
You would take the 30 from the angle and make an equation with the x+3
Steps are:
X+3=30
Subtract 3 from 30 to get you 27
Therefore x= 27
Answer:
33%
Step-by-step explanation:
Let's find the answer by using the following formula:
(final amount)=(initial amount)+((initial amount)*(percent increase)) so:
665=500+(500*X) where X=percent increase
Solving, we have:
X=(665-500)/500
X=0.33=33%
In conclusion, the percent increase was 33%.
