Question: A triangular wedge of negligible weight is to be driven between block B and block C. If the coefficient of friction between the blocks is zero and between the block & floor is 0.45. In that case the value of friction will be, Kinetic friction = 0.2 50 N = 10 N. The sliding or kinetic friction is less than static friction because of the interlocking of irregularities in the two surfaces. RA = 120 KN answer, Take a moment at point A Remember that is always measured from the origin counterclockwise. Other examples include a rock balance sculpture, or a stack of blocks in the game of Jenga, so long as the sculpture or stack of blocks is not in the state of collapsing. because of the interlocking of irregularities in the two surfaces. 5.2 EQUILIBRIUM OF FORCES Equilibrium is defined as the condition of a body, which is subjected to a force system whose resultant force is equal to zero. When the line of action of all the forces do not lie in one plane, is called Non-coplanar force system. Force is represented as a vector .i.e an arrow with its magnitude. In the static part when we say that a body is in equilibrium, what we mean is that the body is not moving at all even though there may be forces acting on it. A ladder of weight W rests against a smooth vertical wall at one end and one rough horizontal ground at the other. Without friction, no rolling is possible. Discussion of the subject areas of statics and dynamics covers such topics as engineering applications of the principles of static equilibrium of force systems acting on particles and rigid bodies; structural analysis of Engineering Mechanics Dynamics Hibbeler 11th Edition Solutions Two force systems are equivalent if they result in the same resultant force and the same resultant moment.
