Series and Parallel Spring Forces Calculator
Series and Parallel Spring Forces Calculator. When more than one spring is being used in a design, they are either in series, meaning one after another, or in parallel, meaning side by side, or a combination of both.

Internal Combustion Engine Flywheel To Drive Machine Formula and Calculator
The torque (T ) delivered by an internal combustion engine is a function of the rotation angle (θ). In fact, for a fourstroke engine, power is delivered during only one of the four 180◦ cycles. For the other three cycles, the inertia and thermodynamic processes of the system are slowing the engine down.

Flywheel Inertial Energy Formula and Calculator
Flywheels store and release the energy of rotation, called inertial energy. The primary purpose of a flywheel is to regulate the speed of a machine. It does this through the amount of inertia contained in the flywheel, specifically the mass moment of inertia.

Poiseuille Law Formula and Calculator
This equation is known as Poiseuille’s law, and this flow is called Hagen  Poiseuille the pressure drops and thus the required pumping power is proportional to the length of the pipe and the viscosity of the fluid, but it is inversely proportional to the fourth power of the radius (or diameter) of the pipe.

Marin Endurance Limit Equations and Calculator
Marin Factors for Corrected Endurance Limit Fatigue The endurance limit (S'e) determined using Eq. 2 that is established from fatigue tests on a standard test specimen must be modified for factors that will usually be different for an actual machine element.

Stresses in Universal Knuckle Joint Formulas and Calculator
Stresses in Universal Knuckle Joint. Universal joints are a mechanical form of coupling, originally known as a Cardan or Hooke's coupling, is used for connecting two shafts the axes of which are not in line with each other, but which merely intersect at a point. There are many different designs of universal joints or couplings, which are based on the principle embodied in the original design.

Moments and Reactions for Rectangular Plates using Finite Difference Method
Moments and Reactions for Rectangular Plates using the Finite Difference Method. This book of monograph presents a series of tables containing computed data for use in the design of components of structures which can be idealized as rectangular plates or slabs. Typical examples are wall and footing panels of counterfort retaining walls.

Pipe Flow Gradual Size Enlargement Formula and Calculator
Gradual enlargement causes less energy loss than sudden enlargement because it causes less turbulence. Diffusers are gradual enlargement device. Velocity decreases while pressure increases. Gradual enlargements generally have a conical section that joins two different pipe diameters.

Fluid Energy Loss in Fittings and Valves Formula, Calculator and Tables
Fluid Energy Loss in Fittings and Valves Formula, Calculator and Tables. There are two standard ways to calculate the energy lost in fittings and valves: the resistance coefficient method, and the equivalent length method. The method chosen will depend on what information is provided with the fitting to be analyzed
