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 another.
The load will be attached to a 2" 'pulley'.
The 3/16" cable is represented by #1, Purple (90") and 2, Green (112"). Figure 1
Segment 2 is angled downward where it meets segment 1 which is horizontal/level.
Ideally I would install the cable in a single run that would loop through an eyelet (B") to create the 90 degree angle.
If doing it that way is not advisable, I would use two sets of thimbles, wire rope clips etc. to create the 90 degree leg. And "A" would then require a turnbuckle (connected to an eyebolt).
In all cases, "C" would consist of an eyebolt and a turnbuckle attached to a 5.7mm thick u shaped bracket made of Q235B carbon steel, mounted to a brick wall using (2) 3/8" x 3" Hex Nut Sleeve Anchor Expansion Bolts.
Because the angle of segment 2 (green) is somewhat steep, I will use an electric hoist to control its descent (or in a rare instance, pull the load up to a higher floor).
To measure the cable tension I can either use a Digital Force Gauge Push and Pull Meter (and somehow measure the tension after install) or a Digital Hanging Scale rigged to a wire rope clip to temporarily bypass the turnbuckle.
FYI the electric hoist is only available at point C and the wall along the #1 purple segment cannot be used for mounting.
My questions are:
1 Is it advisable to use a single eyebolt to create the 90 degree turn?
2 What are the minimum ratings for the mounting hardware and rigging?
