The atmosphere is a blanket […]

What is a load sensing valve? The load sensing valve (L.S.V.) serves the purpose of automatically adapting the brake pressure and therefore the brake force according to the load of the vehicle. What does load sensing mean? Load-sensing describes a type of variable pump control used in open circuits. It is also termed this because […]

What is it called when a straw bends in water? This bending of light, called refraction, causes the straw to look broken​1​. The portion of the straw that is submerged in water also appears to be wider than the portion of the straw above the water. Why does a spoon look broken in the water? […]
