Hi, I am investigating the possibility of using 2 oppositely polarised electromagnetics to locate 2 moving bodies into the correct position as they move towards each other and would appreciate some thoughts on the feasibility of the solution and ways it might be improved. I am proposing using...

thank you very much for your thoughts, very useful! Thanks

Hi all I am doing a university module on vehicle dynamics and wish to clarify/enhance my understanding of vehicle handling and the effects of weight transfer. Here are a points based some past exam questions and my answers, if anyone can spot a mistake or would like to add anything this would...

Homework Statement Hey. I've posted a few questions around here lately, and really appreciate any help! thanks Right, attached is an image showing a simple pump system. pump inlet gauge pressure = Pi = -34.2 kPa nozzle diameter = 5cm rho = 1000kg/m3 Calculate the flow rate 2. The...

Homework Statement An enclosed vertical tube rotates about its vertical axis at w=3000rpm. At the axis, r=0, P=1.5bar and T=293K. What is the pressure distribution as a function of r? And hence calculate the pressure at r=2m. The Attempt at a Solution I have seen this type of questions...

thank you, I think that helps!

Homework Statement I am having trouble understanding problems involving the force and bending moment on a submerged surface. The problem in question is as follows: variation in density of a muddy lake is given as rho = rhoo + kh, where rhoo = 1000, k = 100 and h = depth of lake. A...

i9 realize I've been being a fool. think the output voltage can vary anywhere between -15V and +15V; a range of 30V. An output of +3V is therefore 18V above the lower -15 level and 12V below the +15 level. In other words, the potential divider must divide the 30V total in the ratio 12/18. The...

i think i might be on to something, maybe someone can confirm if this is right, and if it is eplaiin why. i think it goes +15v into R1 = 5k into r2 = 7.5 k and -15V out. then the output measuered between R1 and R2 = 3v. I've been messing around on a simulator and it works, but i don't know why...

i've spent all day thinking about the above problems to no avail. can no one help me? thank you

potentiometer question hey there i hate coming online to ask for help but i am well and truly stuck! attached is an image containing 2 potential divider setups. i have a few questions about them, and any help would be appreciated! a) for the first setup, A, how could the 10k pot be...
