Homework Statement
Please see attached photos. I've been drawing and re-drawing diagrams but I'm at a loss. For part a, I've tried a right triangle using the top cable as the hypotenuse. I've tried the force equation (ƩF=ma) but I don't think that's right. I just can't get a start...
Homework Statement
Please see attached photo. It is problem 54.
My difficulty is that I am not sure if I marked out the correct forces in the work-force equation. Without the height, I can't find the angle. I was going to use the formula: Δx=radius (times) Δθ
However, I'm not even sure this is...
Homework Statement
A 1200-N uniform boom at ∅=55° to the horizontal is supported by a cable at an angle θ=25.0° to the horizontal. The boom is pivoted at the bottom and an object of weight 2 000 N hangs from its top.
Find (a) the tension in the support cable and (b) the horizontal and...
