    Question about a Mass-Spring-Damper

    Homework Statement 1) The schematic diagram for the suspension system at one corner of a road vehicle is shown below. The displacement of the road wheel is denoted x, and the resultant displacement of the vehicle body is y. IMAGE - http://imgur.com/VxKx5Qq Values of the spring rate, k, damping...

    Finding the shear stress and angle of twist in hollow shaft

    No, the image is for Part 1, Part 2 shown under it is unrelated. The Part 1 question simply states titanium, and expects me to find out what the properties are.

    Finding the shear stress and angle of twist in hollow shaft

    MODERATOR NOTE: THIS THREAD WAS ORIGINALLY IN ANOTHER FORUM, SO THERE IS NO TEMPLATE. I have a hollow shaft made of a titanium alloy, Shear Modulus "G". The shaft has a wall thickness of 3.2mm and an inner diameter of 20mm. The shaft looks as show in the attached image. A torque T of 232 Nmm...

    Calculating shear stress in a beam?

    The equation for shear stress as I know it is VQ/It where V is the shear force, Q is the first moment of area(?), I is moment of inertia and t is the length of the section in question. My question is, is there a general formula for Q? In my Solid Mechanics notes I've written that Q = ∫y.dA but...

    How do I calculate moment of inertia in a wheel?

    That actually does! Thanks a million! I won't be able to do that for my interim report tomorrow but this will help a great deal :)

    How do I calculate moment of inertia in a wheel?

    Little to no experience other than basic theory. I'm doing this as my final project for my bachelors, and my project supervisor says I don't need to make it over complex because I just don't have the experience

    How do I calculate moment of inertia in a wheel?

    Nope, I do not have access to any testing equipment right now. I'm assuming its a perfect system, just need the theory right now. Testing and implementation when I have access to materials :)

    How do I calculate moment of inertia in a wheel?

    What I have are two wheels, weight assumed at 50 kg overall for both, joined by an axle. The wheels are 900 mm apart from the centre of one tire to the centre of the other. The diameter of the tire is 690 mm. How do I calculate the moment of inertia in order to find the torque in the centre of...

    Explanation of the mechanics of a rack and pinion system?

    Hello everybody, I'm a final year student in mechanical engineering. For my final year project, I'm designing a spring system to store energy when stopping a hand wagon and use this to boost the wagon when starting. This involves a pinion attached to the axle of rotation for the wheels, and a...
