Thanks very much. The motors are micro metal gear motors so I'll have a look and see if they have that information.

Hey Guys, so I'm just in need of some help in relation to finding the output current after the voltage has been dropped to 6V. The circuit has an input voltage of 24V and I've attached a photo of my circuit diagram. Hopefully I haven't made any errors in that, but I've tested the circuit and it...

No problems. Thanks for all your help! Alex

I think I understand now. Once I find the torque how do I know if this will cause the structure to collapse though? Sorry about all the questions! You are extremely helpful!

Ok I think I get that but how does finding the normal forces help me find the force used in the formula T=f x r x sinQ? Or am I missing something?

Instead of me explaining is this how you find the normal forces? http://bendingmomentdiagram.com/tutorials/calculating-reactions-at-supports/ If use this to find my normal force on each end of beam 1, how does this help me to find the force at the end of beam 2? Just to confirm about finding...

The further from A the greater the torque being applied I guess. So that would mean my force at the end of beam 2 would be greater. This is where I am stuck in finding that force. Thanks, Alex

Yes both beams are on support A. It was meant to be a challenging question I think. Yes, it's just torque that we are trying to find but obviously there's a few things to find before that. Could I just say that because the beam is uniform, that by finding the centre point of beam 2 and using...

Thanks for the replies. Haruspex - Yes that's almost what I mean. I'm not sure if this is what you already thought, but beam 2 is connected and right beside beam 1 except beam 2 only goes halfway out. Beam 2 will therefore be twisting and pulling beam 1 down causing it to fail. Also as you...

Homework Statement Hi guys, I'm currently working on a homework question but I'm a little bit stuck although I do know what I'm meant to be doing. My question asks me to find the torque being caused by a beam pulling down on another. I'll explain a little more the context of it - there is one...

Hi guys, just wanted to introduce myself to this forum. I think I will learn a lot from being on this site! Alex

I'll definitely make sure I use this again when I'm having trouble! It seems so obvious now haha. Thanks

Hi Anemone, thanks very much for your help. I actually managed to find all of the intersection points after a bit of thinking. For the y=cosx and y=tanx one I used the quadratic formula and then found the 2 x intercepts, although only one is valid due to it being in the 1st quadrant. I then...

Hi guys, I'm new to this site and it seems like it will be a great resource when I'm stuck on a problem. I'll firstly set out the question and then add in my working so far. Question: I was firstly asked to graph the trigonometric functions y=sinx, y=cosx and y=tanx in the interval where x is...
