# PWR-002 — Relative strength: learner worksheet Release: Revision 7T · Full Tutorial Edition Estimated time: Estimated 18 min reading and worksheet pass Difficulty: Introductory Equipment: Basic stationery or digital tools — The four-case fixture in this record; Paper or a blank calculation area; A calculator, optional; The answer key, kept hidden until each calculation is complete Space: Desk / seated Automated structural checklist: 10 of 10 structural checks present Evidence quality/context: G2; Focused research depth Automated method-quality band: Established Method-rating basis: Structure coverage, instruction/check specificity, alternative distinctness, source troubleshooting, comparison depth and whether purpose/check fields are authored rather than derived. Editorial review: Pending manual editorial sign off ## Before you begin - [ ] I read the tutorial authority and stop conditions. - [ ] I have the required equipment/space or a declared accessible alternative. ## Canonical source context Relative strength is not a new strength test. It is a way to place an already-known absolute result beside a declared size adjustment. This pack uses fictional values, keeps the original force visible, and shows why a ratio can change even when force does not. Target outcome: Define relative strength without inheriting mythology or broader claims. Explain what the current evidence supports and what it does not establish. Use the declared measurement boundary and recognise misleading proxies. Complete the current learning route without converting it into unauthorised capability practice. Make a retention, transfer, maintenance, provider or stop decision without overclaiming. ### Authority and setup conditions - Governance ceiling: explanation and static fictional record analysis only. Capability self-practice, live administration, protocol delivery and efficacy claims are not authorised until the recorded next_gate adjudication changes. - Use only the supplied fictional force and body-mass values. Do not lift, squeeze, diet, alter body mass or generate a new personal result. - The ratio is a teaching calculation for one declared setup; it is not a strength, health, readiness, worth or treatment score. ### Required or supplied materials - The four-case fixture in this record - Paper or a blank calculation area - A calculator, optional - The answer key, kept hidden until each calculation is complete ### Supplied fixture Calculate the simple ratio for each fictional case, then decide which cases can be compared fairly. | Case | Task | Equipment and posture | Support | Absolute force (N) | Body mass (kg) | | --- | --- | --- | --- | --- | --- | | A | Isometric handle pull | Rig R1, seated | Back support only | 600 | 75 | | B | Isometric handle pull | Rig R1, seated | Back support only | 600 | 60 | | C | Isometric handle pull | Rig R1, seated | Back support only | 660 | 75 | | D | Isometric handle pull | Rig R2, semi-reclined | Back and arm support | 600 | 75 | ## 1. Write the formula: simple ratio = force in newtons divided by body… Write the formula: simple ratio = force in newtons divided by body mass in kilograms. Why: “Write the formula: simple ratio = force in newtons divided by body mass in kilograms” creates the auditable value, condition or statement needed for the tutorial’s later comparison and conclusion. Success check: A legible entry directly completes “Write the formula: simple ratio = force in newtons divided by body mass in kilograms” and records the requested condition, decision or boundary without adding a new claim. Accessible alternative: Complete the same research action — “Write the formula: simple ratio = force in newtons divided by body mass in kilograms.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “A legible entry directly completes “Write the formula: simple ratio = force in newtons divided by body mass in kilograms” and records the requested condition, decision or boundary without adding a new claim.” Do not convert the research task into capability practice.
