A single cylinder horizontal engine runs at 120 r.p.m. The length of stroke is 400 mm. The mass ofthe revolving parts assumed concentrated at the crank pin is 100 kg and mass of the reciprocatingparts is 150 kg. Determine the magnitude of the balancing mass required to be placed opposite tothe crank at a radius of 150mm which is equivalent to all the revolving and 2/3rd of the reciprocating masses. If the crank turns 30° from the inner dead centre, find the magnitude of the unbalancedforce due to the balancing mass solve graphically
The figure below shows a cylinder, which is rotating in clockwise direction. A lever is pushing onto the cylinder, thus exerting a braking torque. The lever itself is loaded by a force FE . a) Draw the free-body diagram of the lever, determine the direction of the kinetic friction force.

The hand brake for a bicycle is shown. Portions DE and FG are free to rotate on bolt A which is screwed into the frame BC of the bicycle. The brake is actuated by a shielded cable where T1 is applied to point E and T2 is applied to point G. A spring having 40 N compressive force is placed between points E and G so that the brake stays open when it is not being used. Assume the change in the spring's force is negligible when the brake is actuated to produce the F = 100 N forces at points D and F. Determine the necessary cable forces T1 in N.
A large symmetrical drum for drying sand is operated by the geared motor drive shown. If the mass of the sand is 740 kg and an average gear-tooth force of 2.60 kN is supplied by the motor pinion A to the drum gear normal to the contacting surfaces at B, calculate the average offset X of the center of mass G of the sand from the vertical centerline.

The cranks and connecting rods of a four cylinder in-line engine running at 2000 rpm are 60mm and 240mm each respectively. The cylinders are spaced 150 mm apart. If the cylinders are numbered 1 to 4 in sequence from one end, the cranks appear at intervals of 90º in an end view in the order 1-4-2-3.The reciprocating mass for each cylinder is 15 kg. Determine (i) unbalanced primary and secondary forces, (ii) unbalanced primary and secondary couples with reference to central plane of the engine
