Kindly check the attached image below to see the step by step explanation to the question above.
Describe the relationships between load, shear force, and bending moment.
1 answer:
Answer:
the relation between load , shear force and bending moment is
shear force in a beam is calculated by the differentiation of the loading with respect to distance or length of the beam
Bending moment in a beam is define as the change of shear force diagram with respect to the length of the beam.
and where as
where V is the shear force , x is the distance in the beam , M is the bending moment and w is the loading on the beam.

Answer:
a = 40
b = 29
Explanation:
Give a place holder for the numbers that we don't know.
Lets call the two numbers a and b.
From the given info, we can write an expression and solve it:
"one number is 11 more than another number"
a = 11 + b
from this, we know that a > b.
''three times the larger number exceeds four times the smaller number by 4"
3a = 4b + 4
Now we have 2 equations, we can use them to solve using whatever method you want.
a = 11 + b
3a = 4b + 4
I will be using matrices RREF to solve for this.
a - b = 11
3a - 4b = 4
a = 40
b = 29
Answer: LED have the lowest cost of operation.
Explanation:
If we ignore the initial procurement cost of the items the operational cost of any device consuming electricity is given by
Among the three item's LED consumes the lowest power to give the same level of brightness as compared to the other 2 item's thus LED's shall have the lowest operational cost.
