Answer
any Two questions 2x5=10 M
1. The turning moment curve for an engine is
represented by the equation, T = (20 000 + 9500 sin 2θ – 5700 cos 2θ) N-m,
where θ is the angle moved by the crank from inner dead centre. If the
resisting torque is constant, find: 1. Power developed by the engine ; 2.
Moment of inertia of flywheel in kg-m2, if the total fluctuation of speed is
not exceed 1% of mean speed which is 180 r.p.m; and 3. Angular acceleration of
the flywheel when the crank has turned through 45° from inner dead centre.
2. The turning moment
diagram of a four stroke engine may be assumed for the sake of simplicity to be
represented by four triangles in each stroke. The areas of these triangles are
as follows: Suction stroke = 5 × 10–5 m2; Compression stroke = 21 ×
10–5 m2; Expansion stroke =
85 × 10–5 m2; Exhaust
stroke = 8 × 10–5 m2. All the areas excepting expression stroke are
negative. Each m2 of area represents 14 MN-m of work. Assuming the
resisting torque to be constant, determine the moment of inertia of the
flywheel to keep the speed between 98 r.p.m. and 102 r.p.m. Also find the size
of a rim-type flywheel based on the minimum material criterion, given that
density of flywheel material is 8150 kg/m3 ; the allowable tensile
stress of the flywheel material is 7.5 MPa. The rim cross-section is rectangular;
one side being four times the length of the other.
3. Derive the equation for hartnell governor
4. A shaft carries four
masses A, B, C and D of magnitude 200 kg, 300 kg,400 kg and 200 kg respectively
and revolving at radii 80 mm, 70 mm, 60 mm and 80 mm in planes measured from A
at 300 mm, 400 mm and 700 mm. The angles between the cranks measured
anticlockwise are A to B 45°, B to C 70° and C to D 120°. The balancing masses
are to be placed in planes X and Y. The distance between the planes A and X is
100 mm, between X and Y is 400mm and between Y and D is 200 mm. If the
balancing masses revolve at a radius of 100 mm, find their magnitudes and
angular positions.
