The paper will fetch you 70 marks. There are no sections, and the student must answer any four questions from a total of 6. The first question is compulsory. Some of the questions are: enumerate the characteristics of a force, differentiate between statics, kinetic and kinematic, explain the principle of transmissibility of forces, define term resultant of a force system, define the term free body diagram and state the importance of the diagram, define product of inertia and its properties, state and explain the concepts of principal axis and principal moment of inertia, what is reversibility of machine and how should the efficiency for reversible machine be greater than 50%, show by graph variation of mechanical advantage with load as well as variation of efficiency with load. There are also mathematical problems such as: a roller of weight 500N rests on a smooth inclined plane and is kept free from rolling down by a string, as in diagram provided, from the basis of this diagram, calculate the tension in the string and the reaction at the point of contact.
