How can I distribute a 3.6 kg load over multiple nails using a string?
I'm trying to solve a practical problem with what feels like should be basic physics. I've guessed that this problem might be about vectors, pulleys and trigonometry, but it's knowledge which I lack, and I'd like to learn. Asking this on the Physics…

Tension and Shear on L-Bracket Offset From Wall
I’m planning to mount a mantle on a brick fireplace wall using two iron L-brackets that are 5” wide and 1/4” thick. Each bracket has four 5/16” mounting holes…two at the top and two at the bottom. The bracket is 5-3/4” deep including the lip at the…

Maximum tensile and shear loads on screw
I'm using a screw in an application where I want to have a high degree of confidence the screw will not fail, and I want to be sure I'm calculating the maximum tensile and shear loads it can sustain correctly as well as the tension and shear it's…

Gap in a statically indeterminate problem
How to solve problem, if we don't know $\Delta$.
Prior to loading, a gap exists between the column face and the absolutely rigid plate .
Find the allowable value of the gap $\Delta$ from the strength condition;
Draw the epuples $N$, $\sigma$, $w$…

Steel cable trolley, best practices and weight limits
I asked "AI" to confirm metrics from other sources and it gave numerous formulas and dubious answers, none of which inspired confidence.
The goal is to set up a cable system to transport a load of no more than 200 lbs. from one floor to…

What does it mean for an item's tensile strength to be "rated"?
I found a 40ft. length of rope for sale at the dollar store. Not having high expectations to start with, I examined the packaging closer out of curiosity. The front of the label states that the rope has 200lbs of tensile strength... Not all that…

What Tension Force will make the bolt to pull out of the nut?
I know how to calculate the bolt capacity for tension and shear, also how to check bolt bearing against different elelment such as steel or aluminum.
There is a hanging bolt by which a bar is hanging and the bolt subject to pure tension loads.
How…

How to connect / branch two metal wire cables at 90degree angle
I have a 1mm thick wire cable that's 200cm long.
Using the same cable, at 10cm intervals, I have to branch / tee off at 90degree angles.
Some sort of tee crimp / ferrule comes to mind as a last report, but I'm wondering does a fastener for this…

Bolt tensile load through an "intermediary"?
Following up on this question, does it change anything if the bolted arm is an intermediate arm (e.g. some sort of mating interface like below)? That is, the arm receiving the load is connected to the original arm through a different set of…

How to solve statically indeterminate pulley?
I am working on a wire rope pulley at rest, shown below. The wire rope wraps once around the pulley (180°) and has tension T. The pulley axle is on a sliding track that is up against its hard stop, thus a reaction force R balances the free body…

Quantifying friction for a rope coiled around a cylinder with external loading
The Problem
Consider a massless rope that is coiled around a cylinder with radius $r$.
The shape of the rope's coiling is helical defined by variable curvature $\kappa(s)$ and torsion $\tau(s)$, where $s$ is the arc length parameter starting from…
