MikeHalloran and gearcutter
Thank you both for the insight, that explains the worm being at an angle for the Dutton-Lainson worm gear winch. Now, I'm sure this changes the calculations for the stress at the teeth. Is this something that can easily be calculated by hand (as with the standard...
My textbook (Machine Elements in Mechanical Design 4th ed. by Robert Mott, ISBN: 0-13-061885-3) says that a low cost method of creating a wormgear set is to use a worm with a spur gear. However, it doesn't say how to do this. I'm assuming it must have the same pitch but other than that, I'm not...
Arm 2 is in bending due to the platform weight and wind load and it's own weight. It bends about the pivot point on the left side.
Again, I'm only interested in the front view so that I can either draw a shear and bending moment diagram or so I can cut a section at the hinge (pivot point on...
Yes, that's correct. The pin, arm 1, and arm 2 are all welded together so they rotate together as one piece.
Yes, I understand that the pin is under torsion and that should be a fairly easy calculation but my main goal is to cut a section through the pin (looking at the front view) and...
Sorry about the lack of info...
Fy and Fx are externally applied forces acting on arm 1. All of the forces are known except for Rx and Ry which are easily solved using the static equilibrium equations.
The arm is similar to a cantilever beam. It pivots about the pin where Ry and Rx act. Fx...
I'm still very much a newbie and would really like some help. I've looked through my old Strength of Materials textbook but couldn't find an example of how to draw V-M diagrams for a hinged beam.
My goal is to calculate the stress at the slot. Not sure if I'm looking at solving this...
