Achilles tendon rupture.To develop and validate a new patient-reported instrument for measuring outcome after treatment . All other values required in order to carry out calculations of prestress losses in accordance with the design code are obtained directly from the model. On calculators with Slider Controls, drag slider tab to get close, then use keyboard cursor keys to fine tune. It is used in bridges, buildings, skyscrapers, homes, warehouses, and foundations to increase the strength of a concrete structure. Area Moment of Inertia is defined as a moment about the centroidal axis without considering mass. Young's Modulus given Deflection Due to Prestressing for a Parabolic Tendon Solution STEP 0: Pre-Calculation Summary Formula Used Young's Modulus = (5/384)* ( (Upward thrust*Span length^4)/ (Deflection*Second moment of area)) E = (5/384)* ( (Wup*L^4)/ (*I)) This formula uses 5 Variables Variables Used
