Lcross took pictures of the impact, which threw up clouds of lunar debris. 2009 China's first lunar probe, Chang'e 1, named after a goddess who flies to the moon, was steered into the lunar surface at the end of its mission. Future probes will aim for a soft landing. Topics
Slipper clutch also known as slider clutch is a special clutch which is in most high end performance motorcycles. What the clutch essentially does is it considerably reduces the effects of engine braking when the rider downshifts too quickly.
The clutch allows us to smoothly engage a spinning engine to a non-spinning transmission by controlling the slippage between them. To understand how a clutch works, it helps to know a little bit about friction, which is a measure of how hard it is to slide one object over another. Friction is caused by the peaks and valleys that are part of every surface -- even very smooth surfaces still have microscopic peaks and valleys.
