@russ watters - Ah. I see. Thank you very much. @Dr Lots-o'watts - Thank you, but I prefer not to buy things over the internet.

I'm trying to build a tesla turbine. I'm trying to follow the instructions here. However, the turbine calls for neodymium magnets, which I can't seem to find. Would other magnets work?

I see. Thank you very much :)

Homework Statement A stone is thrown vertically into the air from a tower 110 ft. high at the same time that a second stone is thrown upward from the ground. The initial velocity of the first stone is 60 ft/s and that of the second stone 85 ft/s. When and where will the stones be at the same...

I meant to say horizontal component of tension or tension sin 60. Sorry and thank you very much.

Wouldn't the horizontal forces be equal since the tension and the beam are in equilibrium? Ok. Oh sorry. I forgot to put the distance. 2744N x 2.2 + 245N x 1.1 - Ty x 2.2 = 0

Let me try... Horizontal force of hinge = Horizontal component of tension / Tension sin 60 Vertical component of tension + Vertical force of hinge = 2989 N 2744 N x 2.2 + 245 x 1.1 = Vertical component of tension / Tension sin 30 Is that right?

Homework Statement Consider the following cantilevered beam: The beam has a mass of m = 25 kg and is 2.2 meters long. The suspended block has a mass M = 280 kg and the supporting cable makes an angle of 30 degrees with the beam. Determine the force that the wall exerts on the beam at the...
