Beam 1

Bam 2

3. Two beams have the same length and are made of the same material. They also have the same

height of 8 cm. The rest of the cross-section dimensions can be seen in the above picture:

a)

Both beams are stretched with the same pure tensile load of P. Which one will have

the higher stress? Explain and show any calculations.

$

b) Assuming there is no plastic deformation, what material property would you need

to know in order to calculate how much the beam stretches while under load?

c) If Beam 2 is loaded with P-10KN, what is the stress in the original units on beam 2?

What is the stress in MPa?

Explain or show calculation.
