A floor is supported by 75mm x 200mm wooden joists spaced @ 400 mm on centers with an effective span of 3m. The total floor load transmitted to the joist is 5 Kpa. Weight of wood 6.3 KN/m3. Ew = 12x...

A floor is supported by 75mm x 200mm wooden joists spaced @ 400 mm on centers with an effective span of
3m. The total floor load transmitted to the joist is 5 Kpa. Weight of wood 6.3 KN/m3. Ew = 12x 10^3MPa.
a. Determine the maximum flexural stress of the beam.
b. Determine the maximum shearing stress of the beam.
c. Determine the maximum deflection of the beam.
