Photosynthetically active radiation PARLumen, and Radiant Flux conversion Calculator This calculates lighting as it is relevant between plants and humans using actual spectrum curves. This should be accurate for LED based grow lights as well as any other type of lighting as long as the spectrum is known. The lumen and PAR dependent numbers are calculated based on actual studies that measured the real world curves.

If your brakes fail, the result can be disastrous. Brakes are actually energy conversion devices, which convert the kinetic energy momentum of your vehicle into thermal energy heat.

When you step on the brakes, you command a stopping force ten times as powerful as the force that puts the car in motion. The braking system can exert thousands of pounds of pressure on each of the four brakes. Since Plus 8s or all cars Morgans have been fitted Pub 375 notes dual circuit master cylinder systems, with each the front and the rear wheels braked by a separate subsystem.

That way, if one subsystem fails, the other can provide life-saving braking power.

These are infinitely safer than earlier braking systems. I counsel you to ignore or caution anyone who suggests a single circuit system be maintained rather than replaced.

To stop a horse drawn carriage, the driver would pull on a lever which would rub on the wheel. The brake system is composed of the following basic components: Steel "brake lines" and flexible "brake hoses" connect the master cylinder to the "slave cylinders" located at the wheel.

Brake fluid, specially designed to work in extreme conditions, fills the system. Disc brakes have been used for years for front wheel applications, and on many older cars are fast replacing drum brakes on the rear wheels.

This is generally due to their simpler design, lighter weight and better braking performance. The greatest advantage of disc brakes is that they provide significantly better resistance to "brake fade" compared to drum type braking systems. Brake fade is a temporary condition caused by high temperatures generated by repeated hard braking.

It occurs when the pads or shoes "glaze" due to the great pressure and heat of hard use. Once they cool, the condition subsides.

Disc brakes allow greater air ventilation cooling compared to drum brakes. Drum brakes are not internally ventilated because if they were, water could accumulate in them.

Disc brakes can rapidly fling off any water that they are exposed to, and so they can be well ventilated. Morgan rotor discs are quite thick which requires higher temperatures to heat but are also difficult to cool for the same reason. High performance disc brakes have drilled or slotted holes through the face of the rotor, which helps to prevent the pads from "glazing" becoming hardened due to heat.

Many suppliers sell ventilated discs for racing applications. Disc Brakes by Lorne Goldman Disc brakes use a clamping action to produce friction between the "rotor" and the "pads" mounted in the "caliper" attached to the suspension members.

Inside the calipers, pistons press against the pads due to pressure generated in the master cylinder.

Total Light output:

The pads then rub against the rotor, slowing the vehicle. Disc brakes work using much the same basic principle as the brakes on a bicycle; as the caliper pinches the wheel with pads on both sides, it slows the bicycle. Disc brakes offer higher performance braking simpler design, lighter weight, and better resistance to water interference than drum brakes.

Disc brakes, like many automotive innovations, were originally developed for auto racing, but are now standard equipment on the front wheels of all Morgans and the rear brakes are of the "drum" type. Drum brakes use two semi-circular shoes to press outward against the inner surfaces of a steel drum.

The older cars have drum brakes on all four wheels. Libra Motive and other suppliers sell a rear disc brake conversion kit. Because disc brakes can fling off water more easily than drum brakes, they work much better in wet conditions. This is not to say that water does not affect them, it definitely does.

If you splash through a puddle and then try to apply the brakes, your brakes may not work at all for a few seconds! Disc brakes also allow better airflow cooling, which also increases their effectiveness.Steve's Pub is a bartender simulator game for virtual reality with not too realistic physics and a lot of fun!
