You need that clamp you mentioned previously. Preferably, it should hook to the other side of that wall.tbaron27 said:Make sense?

Can you put a 300 pound counterweight on top of the platform, a ways back from the face of the wall? If so, that will counter the torque that is trying to rotate the platform clockwise...tbaron27 said:the biggest issue I'm having is how to prevent the structure from rotating off the wall to the right
Fair enough. But you also said this:tbaron27 said:I thought of that but then it pretty much removes the portability factor :-(
If you can extend the top plate (with vertical bracing pieces, right?) farther horizontally past the face of the wall that your support is near, that means you can use a smaller and smaller counterweight. A 50 pound counterweight would have to be how far from the fulcrum to counter the 300 pound weight held by the bottom of the support...?tbaron27 said:For design purposes we need to assume that the width of the wall is infinite
The coefficient of friction should be a given when you know the material and conditions that are involved. You can find typical values on many websites. This wikipedia page sums up the concept of friction, and you get some typical values as well.tbaron27 said:So if I use μ=Fg / FN, I'm still missing a variable in order to solve for μ.
Yes, the idea is to keep the top horizontal piece from rotating clockwise slightly under the torque from the load weight, because such a rotation disengages the contact with the top of the wall, which causes the structure to fall.tbaron27 said:Are you saying to have a spring loaded hinge that creates an acute angle at the top? Then when a load is applied, the acute angle opens but not past 90 degrees? If I'm thinking about this correctly, then the Force equations would still need to be applied but the tension spring would cause a greater friction force correct?
There are several ideas that can help prevent falling in the elderly population. Some suggestions include:
Yes, there are specific exercises that can help prevent falling. Some examples include:
There are a few ways to make the home safer to prevent falls, such as:
Yes, certain medications can increase the risk of falling. These may include sedatives, antidepressants, and medications for high blood pressure or heart conditions. It's important to discuss any potential side effects with a doctor and follow their instructions for taking medication.
Yes, there are lifestyle changes that can help prevent falling, such as:
