Answer:
(a) T = W/2(1-tanθ) (b) 39.81°
Explanation:
(a) The equation for tension (T) can be derived by considering the summation of moment in the clockwise direction. Thus:
Summation of moment in clockwise direction is equivalent to zero. Therefore,
T*l*(sinθ) + W*(l/2)*cosθ - T*l*cosθ = 0
T*l*(cosθ - sinθ) = W*(l/2)*cosθ
T = W*cosθ/2(cosθ - sinθ)
Dividing both the numerator and denominator by cosθ, we have:
T = [W*cosθ/cosθ]/2[(cosθ - sinθ)/cosθ] = W/2(1-tanθ)
(b) If T = 3W, then:
3W = W/2(1-tanθ),
Further simplification and rearrangement lead to:
1 - tanθ = 1/6
tanθ = 1 - (1/6) = 5/6
θ = tan^(-1) 5/6 = 39.81°

The general lighting load for a two-story office building that measures 125 feet by 150 feet is 112, 500 sq ft.
<h3>What is lighting load?</h3>
Lighting loads are the energy used to power electric lights and they make up nearly a third of US commercial building energy use.
Lighting load = n(LW)
where;
- L is length of the building
- W is width of the building
- n is number of story building
For one story building, = 3
For two story building, n = 6
Lighting load = 6 x 125 x 150 = 112, 500 sq ft.
