Graph of Johnson's parabola (plotted in red) against Euler's formula, with the transition point indicated. The area above the curve indicates failure. The Johnson parabola creates a new region of failure. In structural engineering, Johnson's parabolic formula is an empirically based equation for calculating the critical buckling stress of a column.
The designation for a specific motor looks like C6-3.In this example, the letter (C) represents the total impulse range of the motor, the number (6) before the dash represents the average thrust in newtons, and the number (3) after the dash represents the delay in seconds from propelling charge burnout to the firing of the ejection charge (a gas generator composition, usually black powder ...
This formula was derived in 1744 by the Swiss mathematician Leonhard Euler. [2] The column will remain straight for loads less than the critical load. The critical load is the greatest load that will not cause lateral deflection (buckling). For loads greater than the critical load, the column will deflect laterally.
The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .
Johnson Electric (德昌電機控股有限公司) (SEHK: 179) is a provider of motors, actuators, motion subsystems and related electro-mechanical components for automotive, industrial and medical applications. Johnson Electric has manufacturing facilities in 22 countries.
The DOHC 24-valve was used in the Mitsubishi Debonair, 3000GT, and Dodge Stealth producing 222 hp (166 kW; 225 PS) and 205 lb⋅ft (278 N⋅m) of torque with a 10.0:1 compression ratio in naturally aspirated form, and as much as 320 hp (239 kW; 324 PS) and 315 lb⋅ft (427 N⋅m) of torque in turbocharged form.

The first M was a 2.0 L (1,988 cc) version produced from 1965 through 1988. It was a 2-valve SOHC engine. Cylinder bore and stroke was square at 75 mm (2.95 in). Output was 110–115 PS (108–113 bhp; 81–85 kW) at 5,200 to 5600 rpm, depending on specifications and model year.
The cars were raced in 1954 and 1955 while BRM worked on a car for the new Formula One specification of 2.5 litres un-supercharged. By this time the V16-powered cars were running quite reliably, but the demise of the Formula around which they had been based prevented the Mark II cars from making a greater impact.
