Mechanics and Machine Design, Equations and Calculators, Design of Load Carrying Shaft With One Pulley & Supported by two Bearings, Flywheel Effect or Polar Moment of Inertia, Lifting Boom, Davits Application and Design Equations, Large and Small Diameter Lifting Pulley / Drums, Two Lifting Lifting Pulley's Mechanical Advantage, Multiple Pulley's Lifting Mechanical Advantage Mechanical The goal of the study is to design the hydraulic scissors lift to lift up to a height of 1.2 meters and with the carrying capacity of 700 kilograms. The driving mechanism of the lift must be a hydraulic cylinder. Calculations of the inner stresses must be done and a 3D model must be created. It is also necessary to choose the material.

FUNdaMENTALS of Design Topic 6 Power Transmission Elements II. Power Transmission Elements II Screws & gears are transmission elements that warrant a special place in power transmission systems because of the huge range of power leve ls at which they are applied and the very high transmission ratios they can achieve. The first screws were used perhaps by Archimedes in 200 BC as pumps to lift This calculator is designed to calculate torque required to raise the load and torque required to lower the load for Metric Trapezoidal Lead Screw according to ISO-2904-1977 standard. This calculator also can be used to check the self locking capability of lead screws by referring the load lowering torque. Formula for torque to raise the load,
