In a system a lever needs and effort of 200N to lift a load of 350N. The end of the lever arm moves 50cm and the load moves 20cm. a) Determine the mechanical advantage b) Determine the velocity ratio c) Determine the efficiency of the system.
Friction between the piston and cylinder wall can be neglected because the process occurs so slowly. For the air, determine the initial and final pressures in kPa and the boundary work for the process in kJ.
the density of liquid water at 25 c is 997 kgm3 and the specific gravity of solid water ice at 0 c is 0.98. 100 kg of
Shows an electric-circuit which is called a phase-lag network. Derive the transfer function and consider the above bock-diagram of figure (3). You are now required to derive the transfer function Y(s)/R(s), by using the signal flow graph meth..
A centrifugal pump, weighing 600N and operating at 1000 rpm, is mounted on six springs of stiffness 6000 N/m each. Find the maximum permissible unbalance in order to limit the steady-state deflection to 5mmm peak-to-peak.
four forces are applied to a W200x35.9 rolled beam as shown. determine the principal stresses and maximum shearing stress at point a.
a steel ring of mean diameter 250 mm has a square section 2.5 mm by 2.5 mm. it is split by a narrow radial saw cut. the

question 1 a force of 750 n acts on point a in the x direction where the cables ab ac and ad are joined as shown in
The cylinder of a water-cooled reciprocating compressor contains 0.05m^3 of air at 1.01bar. It is compressed isothermally to 8.0 bar. Determine the work input and the amount of heat rejected to the compressor cooling water.
Two slender rods of negligible weight are pin-connected at A and attached to the 18-lb block B and the 80-lb block C as shown. The coefficient of static friction is 0.55 between all surfaces of contact. Determine the range of values of P for which..
