I'm in the process of calculating my combined stress on an axle I am designing, I have calculated the bending and torsional stress, however I need to calculate the direct stress in the axle. In order to do this I need to know the axial thrust in my axle, I understand what axial force is but I am...
I'm currently in the process of designing a bearing housing for an axle. Unfortunately I am not 100% on the diameter of my axle yet but I want to have a clear understanding what tolerances to use on my axle to bearing bore and bearing outer diameter to the bearing housing.
I've looked over the...
Hi,
Really need some help with figuring out the max bending moment in the diagram shown below (I'm aware this is extremely simple but time and stress appear to have the better of me, so any help is appreciated)
I think I've worked out the reactions at each support by doing m=wL as the...
I'm in the process of calculating an axle diameter by using the bending moments which are created with the applied force on the end.
In order to design my axle to be efficient, I believe I need to use the following equation.
Sx = M/Fy
Sx being Plastic Modulus
Fy being Tensile strength of my...
I'm trying to calculate the required gear sizes for the system shown below:
The driven wheel is connected to a 600mm diameter bicycle wheel and the driver wheel connected to a 580 mm long lever arm which has a forward driving force of 40 N.
I want to calculate the most efficient sizing of...
Hi,
I'm trying to calculate the force required to move the wheel on a standard wheelchair from stand still and then consistently over a flat surface?
I understand that this has to with the amount of weight that is trying to be moved, this being the weight of the user (approx. 68kg) and the...
Homework Statement
Mass of elevator = 500kg
Counterweight = 134kg
Force in cable C1 is 1.2kn
Determine the acceleration of the elevator and the force in cable C2
Homework Equations
The Attempt at a Solution
a = f / m
a = (C2 - C1) / m2
a = ((m2 * g) - C1) / m2
a = ((134 * 9.81) -...
