Answer:
T = 2010 N
Explanation:
m = mass of the uniform beam = 150 kg
Force of gravity acting on the beam at its center is given as
W = mg
W = 150 x 9.8
W = 1470 N
T = Tension force in the wire
θ = angle made by the wire with the horizontal = 47° deg
L = length of the beam
From the figure,
AC = L
BC = L/2
From the figure, using equilibrium of torque about point C
T (AC) Sin47 = W (BC)
T L Sin47 = W (L/2)
T Sin47 = W/2
T Sin47 = 1470
T = 2010 N
Answer:
please find the answer in the attached images , in 2 parts, btw thanks for so many points. i hope my answers are correct.
Excess fertilizer use results in nutrient pollution by effecting the nutrition values of the plants we eat.
Cutting down trees more likely to result in air pollution by an increase in greenhouse gases.
Pouring oil in drain creates water pollution which is not a nutrient source.
The correct answer for the question that is being presented above is this one: "256 kpa." <span>If a gas has a gage pressure of 156 kPa, its absolute pressure is approximately 256 kpa. </span>Gauge pressure (GP) is 0 at atmospheric pressure (AP). Absolute pressure= GP + AP. Since atmospheric pressure is ca. 100 kpa; 100 + 156 is 256 kpa.
