Hi, I have been atempting this is a question for a week now and I've been struggling on the final part. The question is below in bold. The tension in a flat belt pulley is 1250N when stationary. Calculate the tension in each side, and the power transmitted, when the belt is on the point of...

Most texts have stress concentration factors for a stepped shaft in tension that has a radius where the smaller shaft meets the larger one such as this reference: http://www.pirate4x4.com/tech/billavista/PR-BV60/Materials/7.jpg I'm looking for a reference (perhaps "Peterson's Stress...

Here I describe one mechanical engineering situation that is very useful in any kind of mechanical and energy consumed industries.I hope you will try to understand it and use it. If you find any difficulty to understand ,feel free to ask me. we can increase efficiency of rotating shaft...

Hello all, I'm new on the forum and will be spending a lot of time here I'm sure, as I am starting a senior design project for my electrical engineering degree. I was wondering if anyone was familiar with a small electric generator, that can be powered by a small RC engine, similar to this...

hi everyone, suppose i have a system of gears where one shaft contains the initial pinion. a drive torque is applied to the pinion shaft so that the pinion then applies a force to the gear its connected to. how would i calculate the forces on the gear shaft? it is a static system (contant...

what formula should i use to calculate the shaft diameter according to the load due to bending and torsion??

There is a rotating shaft which is in contact with a spherical ball. The ball is in contact with an outer casing.The casing is fixed to the ground. I want to estimate the life of the surface which is in contact. There are two surfaces i want to estimate the life for. 1)surface of the...

Hello, I am wondering what the best (and simplest) way to secure a rotor disk to a shaft is. I have a 3" diameter Acrylic disk with a 0.375" hole drilled in it to accept a 0.375" diameter steel shaft. What do you all think? Thanks, Jason O

How can I demagnetize a steel shaft. Heat is not an option. The shaft is 0.6 inches diameter and 3 feet long. Note I have seen several devices for sale that seem extremely expensive. Perhaps, if I know what the actual physical process is, then I can just build a device to demagnetize the...

Hi all, I have a hollow shaft of 2" outside dia to 1.25" inside dia, about 1.5 ft in length.I also have a notch going around the outside periphery of the shaft. The shaft also has 2 holes drilled tranversely through the shaft The shaft will be rotating and will have torsion and probably...

A shaft of light passes through a prism with refracting angle \theta and refractive index n . Let \alpha be the deviation angle of the shaft. Demonstrate that if the shaft of light passes through the prism symetrically the angle \alpha is the least?

on a smaller electric motor the motor output shaft is cylindrical with a hex head insert i am just directly attaching it to a small tire is there a certain type of drive shaft that anyone could recommend i thought about using an old allen wrench but had nothing to hold the drive shaft into...

I've got this shaft you can see in my drawing below, and I'm supposed to find the tension at the locations C and D. At point C I use the following equation: \sigma=\frac{M}{W}=\frac{2500\cdot350}{\frac{50^3\cdot\pi}{32}}=71,3 N/mm^2 This is apparently the right thing to do. 2500 comes from...

First of all this is for marine duty. Iam using a Gear which supplies the shaft flange good for shafts up to 4" in diameter but iam restricted to use a 4.5" shaft. In this case i have to design the flange .. iam struck here could anyone of you please guide me .. how to find out the flange...

Hi there again, I am having problems answering this question A girl wishes to estimate the depth d of a straight mine-shaft. She drops a stone vertically down the shaft and finds that there is an interval of 6 seconds between the instant she dropped the stone at the top of the shaft and...

Ok. assuming that Torque is basically force at an angle (yes that is a very very loose description, I know). would it be fair to assume that net torque would be equal to all torques applied to one rotating shaft? Or are there exceptions to this?

Hello, I'm stuck on this problem and I think its because I am lacking the calculus to get the correct answer. A shaft is turning at 65 rad/s at time = 0. After, its angular acceleration is given by: a= -10.0 rad/s^2 - 5.00t rad/s^3 where t is the elapsed time. Find its angular speed...

A glass marble is dropped down an elevator shaft and hits a thick glass plate on top of an elevatior that is descending at a speed of 2.0 m/s. The marble hits the glass plate 3.0 m below the point from which it was dropped. If the collision is elastic how high will the marble rise, relative to...

Hi. I am trying to figure out how to couple two seperately driven shafts so that the speed of shaft B is always at X RPM greater than the speed of shaft A regardless of what speed A and B are driven at. (X is a constant, but the value depends on some still unfinished math, we will say 500 for...

if I drop a vibrating 440 Hz tuning fork down the elevator shaft of a tall building and when I hear a freq. of 400 Hz, is it possible to determine how far has the tuning fork fallen? My friend said yes but I think no. Am i right?
