2. A group of twenty executives attend a board meeting in a room which measures 20 ft by 20 ft and has a 10 ft ceiling. Assume that each person occupies 2.5 ft and gives out about 375 Btu of heat per hour. Calculate the air temperature rise occurring within 15 min of the start of the conference if the room is completely sealed and insulated. Take c, for air as 0.1715 Btu/lbm°F.

A glue-laminated timber beam is reinforced by carbon fiber reinforced plastic (CFRP) material bonded to its bottom surface. The cross section of the composite beam is shown in figure below. The elastic modulus of the wood is E= 12 GPa and the elastic modulus of the CFRP is 112 GPa. The simply supported beam spans L = 6 m and carries a concentrated load P = 4.4 kN at midspan, see figure below. A If b₁ = 81 mm and b₂ = 35 mm determine: L/2 B L/2 C CFRP b₁ b₂ 250 mm 3 mm
