Surface Tension Problems with Solutions One We are going to solve series of problems with detailed solutions about a topic called surface tension. Surface tension is the property of liquid due to which the liquid surface experiences a tension and they tend to acquire minimum surface area. The center rod is made up of bronze and has a cross-sectional area 0.3 in2. All problems are graded according to difficulty as follows: * Easy; defines general principles; typical of the PE examination; Undoubtedly, many problems can be added to the book but the author tried to mention only more important problems and to prevent increasing volume of the book due to help to feature of portability of the book. Problem # 1 A block of mass m is pulled, via pulley, at constant velocity along a surface inclined at angle Î¸. The bucket started at rest and after being lifted 4 m, it is moving at 4 m/s. What would be the tension in the rope at the top and the bottom of the swing if it were whirled in a vertical circle? I.e. Several problems with solutions and detailed explanations on systems with strings, pulleys and inclined planes are presented. Free body diagrams of forces, forces expressed by their components and Newton's laws are used to solve these problems. Problems involving forces of friction and tension of strings and ropes are also included. T=F C =m v2 r ( ) ( ) 19 N 17 m 19 m s 0.90 kg 2 T = = T Tension vector points inward!
