(This another set of questions from DT, i need the answers rn) (Q1) Volume and Mass of Beam.
The Density of Concrete is 2400 kg/m³.

i) Calculate the area of the end of the beam.
Area of end of Beam=

i) Calculate the volume of a single beam.
Volume of Beam =

i) What is the Mass of one beam? (Volume x Density)
Mass of beam =

(Q2) Sensible Heat.
The Specific Heat Capacity of concrete is 880 J/kg°C
Heat added = specific heat x mass x final/initial

i) How much heat energy (Joules) is needed to heat the beam from freezing point 0°C to maximum temperature of 40°C

ii) How much heat is lost as the beam cools to -5°C from temperature of 20°C overnight.
