A loudspeaker of mass 17.0 kg is suspended a distance of h = 1.80 m below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 3.30 m.
What is the tension in each of the cables?
Tried mg sintheta^2+mgcostheat^2=c^2 but no dice.
Anyone know...
The built-up shaft consists of a pipe AB and solid rod BC. The pipe has an inner diameter of 20 mm and outer diameter of 28 mm. The rod has a diameter of 12 mm. Determine the maximum stress in the shaft.
I have stress=V/A
I picked 12N as V
and Aream I am confused
any help?
I need an equation for shear force ASAP
I am finding average shear stress . i have the equation for that
T=V/A
T being average shear stress A being area and V being Shear force.
Thanks
A car traveling at 16.0 m/s runs out of gas while traveling up a 21.0 degree slope.
How far up the hill will it coast before starting to roll back down?
I tried
1/2mv^2=mgh
1/2(16)^2=9.8h
13.06=h
can anyone confirm if this is correct or not. I;m not sure if I have to use trig to...
The pitcher in a slow-pitch softball game releases the ball at a point 3.0 ft above ground level. A stroboscopic plot of the position of the ball is shown in the figure below, where the readings are 0.25 s apart and the ball is released at t = 0. On the horizontal axis, x1 = 20 ft.

i am still not understanding where you want be to go from here. I realize what you are talking about with the odd numbers. How do i figure out which numbers are the correct ones to use. with A and j having 3 different possiblies
You are confronted with the following formula:
A * [(B + C)(D - E) - F(G*H) ] / J = 10
Knowing that each variable is a unique, single-digit, nonzero number, and that C - B = 1, and H - G = 3, what is the number ABCDEFGHJ, where each letter is a digit? For example, if A = 4, B = 2, and C =...
