21.Friction is a force which opposes motion. Much of the energy supplied to a complicated machine with many moving parts is wasted in overcoming this opposition. The energy is converted into useless heat. The amount thus lost can be considerably reduced the life of the machine prolonged by careful lubrication. This reduction improves the efficiency of the machine. Another way in which friction is reduced is to substitute roller or ball bearings for the earlier type of bearing, in which the surfaces in contact move by sliding. Bearings of these later types are used very extensively in many kinds of modern machinery.
22. Love really is blind when it comes to physical flaws, it would seem.A research conducted by Social studies Center in University of Hawaii at Manoa suggests that when we love someone, we tend to overlook their crooked noses, big tummies or other attributes that might put others off. As a result, husbands and wives think their other halves are more attractive than they really are. No wonder Chinese has the saying that “Beauty lies in the beholder’s eyes”. This phenomenon could also help explain some physically mis-matched couples such as the glamorous Beyonce and Jay-Z, the striking Lara Stone and David Walliams.The so-called “positive illusion” theory comes from an experiment in which researchers asked 70 couples to rate their other halves for attractiveness. Questions included how attractive their husband, wife, boyfriend or girlfriend was to the opposite sex, and how they rated compared with others of the same age. The answers were kept secret to prevent any partners from being upset and distressed. Some of those taking part also rated photos of their partners. In addition, members of the public judged the looks of all 140 men and women taking part.The results revealed that couples view their other halves as being better looking than they really are. Even asking them to rate pictures of their partners did not give them a reality check, the Journal of Social and Personal Relationships reports.With previous studies finding that we view our loved ones as being kinder and more intelligent than they actually are, it does seem that love is blind in all sorts of ways. Those studied were young and had been together on average for just two and a half years. The researchers said that more work was needed to see if those in long marriages were still blind to their partner’s physical flaws.
