Tan(52°) = opposite/adjacent = x/35 ⇒
x = 35 * tan(52°) = 35 * 1.2799 ≈ 44.80
The answer is Hx = ½ Wsin θ cos θ
The explanation for this is:
Analyzing the torques on the bar, with the hinge at the axis of rotation, the formula would be: ∑T = LT – (L/2 sin θ) W = 0
So, T = 1/2 W sin θ. Analyzing the force on the bar, we have: ∑fx = Hx – T cos θ = 0Then put T into the equation, we get:∑T = LT – (L/2 sin θ) W = 0
Answer:
Step-by-step explanation:
4x - 5y= 5
-4x. -4x
-5y = -4x + 5
divide all by -5
y= 4/5x -1
slope is 4/5
y intercept is -1
