picture_as_pdf EMM 108: Workshop Processes and Practice I Examination Workshop paper on the human, environmental and mechanical causes of industrial accidents, the operations involved in making a dust scoop, and an MI 05 metric gauge block set. PDF KES 40.00 picture_as_pdf EMM 301: Mechanics of Machines I First Semester Examination Mechanisms and machine elements paper. Differentiates a lower pair from a higher pair with examples, illustrates all the inversions of a four bar planar linkage and applies one to the coupled wheels of a locomotive. Separates uniform pressure from uniform wear theory in clutch design and finds the maximum and minimum pressure in a single plate clutch from the contact radii and axial force, then describes belt slip and its effect on velocity ratio and states Kennedy's theorem for three kinematic links. Continues with the velocity ratio of a V-belt drive derived to the terms, the maximum power transmissible by a three-belt drive to a blower with the corresponding pulley diameter, the instantaneous centre method applied to a slider crank for piston velocity and connecting rod angular velocity, the efficiency of a screw and the torque needed to raise a load, and the velocity and acceleration diagrams of a four bar chain. PDF KES 40.00 picture_as_pdf EMM 107: Engineering Materials Past Examination Papers Second semester mechanical engineering papers on the alloying elements added to steel and the carbides they form, brass, bronze and duralumin, why titanium and its alloys matter in aerospace, and the features that govern fibre-reinforced composites. PDF KES 40.00 picture_as_pdf EMM 312: Fluid Mechanics III Continuous Assessment Test II Continuous assessment test on compressible flow. Derives Bernoulli's equation for frictionless adiabatic flow of a compressible fluid through a horizontal pipe, defining the adiabatic index, pressure, mass density and velocity. The calculation is a horizontal air venturimeter in a pipe line of given diameter with a fifty millimetre throat, where the mass flow rate follows from the absolute inlet and throat pressures, the inlet temperature, a discharge coefficient of one, the gas constant of two hundred and eighty-seven and an adiabatic index of one point four. PDF KES 40.00 picture_as_pdf EMM 200: Computer Aided Engineering Drawing First Semester Examination Computer-aided drawing paper. Establishes the benefits of using CAD to realise a product, then asks for the function of orthomode, trim and the rectangular and polar array tools, and for the three Boolean operations used in 3D editing. The remaining questions are drawing tasks: isometric projections of a machine part and a bracket to be reproduced with their dimensions, and 3D images to be rebuilt by any suitable method in the correct workspace using the text command.
