Answer:
a) 65.139 MPa
b) 17490 GPa
Explanation:
a) calculate the flexural strength
we now that for a three-point bending test the bending moment will occur at the midsection
Max stress ( flexural strength ) = MY / I
Max stress can be expressed as ; 3/2 * ( F*l / b*d^2 ) ------- ( 1 )
F ( load at fracture ) = 283
l (distance between support point ) = 50
b = 11.6
d = 5.3
substitute given data into equation 1 above
= 3/2 * (( 283 * 50) /( 11.6 * 5.3^2) )
= 3/2 * ( 14150 / 325.844 )
= 3/2 * 43.425 = 65.139 MPa
B ) Determine deflection ( Δ y )
load = 265 N
elastic modulus = 66 GPa
elastic modulus = tensile stress / tensile strain
Tensile stress = Δ y
strain = load = 66 GPa
therefore Δ y = 265 * 66 = 17490 GPa
Answer:
The Floor plan is the heart of a set of construction drawings. It is the one drawing which all trade workers refer. When designing a residence, the floor plan is usually started first.
