    Is a Warm Water Rinse More Effective for Washing Machine Clothes?

    Thanks for the ideas folks. You came up with more than I could. :smile:

    Is a Warm Water Rinse More Effective for Washing Machine Clothes?

    A friend of mine just got a new washing machine. In its manual it states "cold water rinses do not wring out the clothes as well as warm water rinses". She asked what the scientific basis for that is since she had never heard it before. I gave it a lot of thought but for the life of me I...

    Have you witnessed a dazzling Iridium flare in the night sky?

    The most interesting thing I saw through a telescope was Saturn. Number tow is looking at the Lunar surface. :smile:

    What planet/moon would you most like to explore?

    1. If you could visit any planet, moon or asteriod in our solar system which would it be? Io, I would love to see all that activity with Jupiter as a backdrop. 2. If you could visit any star system which would it be? I think I would choose Alpa Centuari, just to see what our solar system...

    Physics of an automobile, suspension, and weight transfer?

    Magnus, you got it! Not to cloud things, but the driveshaft also exerts torgue on the axle, causing the axle to rotate on its pinion and move one wheel up and the other wheel down. Just wanted to point out that auto suspensions are subject to interesting stresses. :smile:

    Physics of an automobile, suspension, and weight transfer?

    With respect to front end lift on a drag car. The lift occurs when the car initially accelerates and still has little forward speed, thus allowing us to discount significant lift caused by airflow. This means that the energy to lift the front end ultimately comes from the engine. If you...

    Physics of an automobile, suspension, and weight transfer?

    Very well put Mr. Parsons. You do need some degree of weight transfer to increase traction. Drag racing, like all motorsports, is about finding the proper balance. :smile:

    Physics of an automobile, suspension, and weight transfer?

    Magnus, the engine's energy used to lift the front end of the car is lost to you for purposes of accelerating. Gravity brings the front end down again and you don't regain the energy. Therefore if you can keep the car front end from lifting, you keep more of the engine's energy available for...

    Physics of an automobile, suspension, and weight transfer?

    Auto suspensions are very interesting. In the case of drag racers, taken to an extreme, some racers have the power to lift the front wheels completely off the ground. This does cost them time and to counter that, they may have "wheelie casters", small wheels that stickout from the the rear of...
