A beam has a rectangular cross section that is 5 inches wide and 1.5 inches tall. The supports are 60 inches apart and with a 12
5 lb person standing in the middle of the beam and it deflects .15 in.
Find the modulus of elasticity
Find the beam deflection
1 answer:
Answer:
The value of Modulus of elasticity E = 85.33 ×

Beam deflection is = 0.15 in
Explanation:
Given data
width = 5 in
Length = 60 in
Mass of the person = 125 lb
Load = 125 × 32 = 4000
We know that moment of inertia is given as


I = 1.40625 
Deflection = 0.15 in
We know that deflection of the beam in this case is given as
Δ = 

E = 85.33 ×

This is the value of Modulus of elasticity.
Beam deflection is = 0.15 in

Answer:
Q = 424523.22 kw
Explanation:

k = 48.9 W/m - K
c = 0.115 KJ/kg- K


T_∞ = 35 degree celcius
velocity of air stream = 15 m/s
D = 40 cm
L = 200 cm
mass flow rate




solving for h

h = 675.6 kw/m^2K

Q = 675.6*2.513*(285-35)
Q = 424523.22 kw
