Final answer:
The student seems confused between MIOSHA rules on ladder scaffolds and a statics physics problem. For the maximum permissible height for ladder jack scaffolds, MIOSHA standards should be consulted, whereas calculations involving ladders, forces, and statics would fall under physics problems requiring the applications of statics.
Step-by-step explanation:
The question you're asking pertains to Physics, specifically within the realm of static equilibrium and forces. However, the question itself seems to be a mix-up because it references MIOSHA rules which relate to occupational safety, specifically the maximum permissible height for ladder jack scaffolds, and then goes on to describe a completely different physics problem unrelated to MIOSHA standards.
For scaffolding height regulations, you would need to consult the specific MIOSHA standards. Yet, it seems you're likely looking for an answer to a statics problem involving a ladder, forces, and tensions. The physics problems you've presented involve calculating forces and tension in different scaffold and ladder setups. I would be able to guide you through the applications of statics in solving these problems if you can provide the right context or the question in its entirety without reference to MIOSHA rules.
