Engineering Fundamentals

Question 1

Deflection of beam with end load equation

Answer 1

d=FL^3/(3E*I)

Deflection = ForceLength^3/(3Modulus of Elasticity * Moment of inertia)

Question 2

Rectangular Cross section moment of inertia equation (bending around x axis)

Answer 2

I=x*y^3/12

Question 3

Rectangular Cross section moment of inertia equation (bending around y axis)

Answer 3

I=x^3*y/12

Question 4

0th Law of Thermodynamics

Answer 4

If two systems, at thermal equilibrium with each other are in thermal equilibrium with a third system, all systems at in equilibrium with each other

Question 5

1st Law of Thermodynamics

Answer 5

Conservation of Energy. It cannot be created or destroyed, only transferred from one form to another.

Question 6

What are ways to maximize beam deflection?

Answer 6

Increase beam length, change beam shape and change material

Question 7

Ways to minimize beam deflection

Answer 7

Decrease beam length, move force close to wall, change material, change beam shape

Question 8

Define modulus of elasticity

Answer 8

Unit measurement of an objects resistance to being deformed elastically when stress is applied
