Saturated Fat Daily Limit
Turns a daily calorie target into grams of saturated fat at the WHO ceiling of 10% of energy and at the stricter 7% the AHA advises for heart risk.

Saturated fat limit: AHA <6% (WHO <10%) of calories
For anyone trying to bring down LDL cholesterol, the American Heart Association suggests keeping saturated fat below 6% of daily calories, which works out to roughly 13 g on a 2,000 kcal diet. The WHO sets a looser ceiling of <10% (≈ 22 g). Industrial trans fats should stay <1%, and in Brazil they're banned outright under RDC 332/2019 (the full ban took effect in 2023); the trans fats that occur naturally in dairy and ruminant meat are still allowed. Example: butter runs about 50% saturated fat, red meat 30–40%, palm oil 50%, and coconut oil ≈ 90% (which is debated, given its MCT/lauric acid content). One easy trap is ultra-processed snacks and cookies, where saturated and trans fats pile up in deceptively small servings. Formula: grams = (kcal · 0.06) / 9 for the AHA target.
Applications: dyslipidemia, cardiovascular prevention, dietary guidelines
This limit shows up across several contexts. It informs dyslipidemia management (since lowering LDL-C cuts atherosclerotic events), cardiovascular prevention under the Brazilian Society of Cardiology (SBC) directives, and national dietary guidelines such as the Guia Alimentar para a População Brasileira, the USDA's, and the NHS's. ANVISA's front-of-pack warning labels (RDC 429/2020) also stamp "alto em gorduras saturadas" on packaged foods that cross the cut-offs (≥ 6 g per 100 g solid / ≥ 3 g per 100 mL liquid).
FAQ
Is coconut oil OK because it's "natural"? No. Coconut oil pushes up LDL just like other saturated fats, and its MCT content doesn't buy it a pass on the limit. The AHA flatly advises against treating it as a heart-healthy oil.
What about dairy saturated fat? There's some evidence, from the PURE study and various meta-analyses, that dairy saturated fat may be neutral for CVD, which points to the food matrix mattering. It still goes into your total, though.
Why are trans fats worse than saturated? Industrial trans fats hit you twice: they raise LDL and lower HDL, and they do it harder per gram. That's why the ceiling drops to <1% and why Brazil banned them.
Replace saturated with what? Swapping in polyunsaturated fats (vegetable oils, nuts, fatty fish) and monounsaturated fats (olive oil) lowers CVD risk. Swapping in refined carbs doesn't.

Initial Prestress Stress
Calculate the allowable initial stress in prestressing steel, σ_pi = coef·f_ptk, from the code coefficient (fraction of strength) and the steel characteristic tensile strength f_ptk (MPa). Prestressing steel is tensioned to a VERY HIGH stress — a significant fraction of its tensile strength — possible because these are HIGH-STRENGTH steels (strands with f_ptk of 1900 MPa, versus ~500 MPa for ordinary reinforcing steel). But there is a LIMIT to the initial stress, set by code for safety and to limit relaxation: typically the lesser of about 0.74·f_ptk and 0.82·f_pyk (yield strength) for low-relaxation steels in pretensioning, with slightly different values for post-tensioning and right after anchorage. Applying a high initial stress is DESIRABLE (more effective prestress, less steel needed), but the code limit prevents tensioning the steel too close to yield (which would reduce safety margin and greatly increase relaxation). This calculation gives the jacking stress to apply (before losses), the starting point of all prestress design. Enter the code coefficient and the steel characteristic strength.

Bearing PV Factor
Calculate the PV factor of a bearing or self-lubricating bushing, PV = P × V, multiplying the specific pressure P (load over projected area) by the sliding velocity V at the surface. The result, in MPa·m/s, is the limiting criterion for selecting materials for non-force-lubricated bearings (sintered bronze bushings, polymers like PTFE and nylon): each material has a maximum allowable PV value, above which the friction heat cannot be dissipated and the bearing fails by melting or accelerated wear. PV is kept below the material limit with a safety margin. Enter the specific pressure and the velocity.
