a gas is contained in a vertical,frictionless piston cylinder device. the piston has a mass of 4kg and cross-sectional area of 35cm^2. A compressed spring above the piston exerts a force of 60N on the piston. if the atmospheric pressure is 95kPa, determine the pressure inside the cylinder.
Gear A rotates with an angular velocity of 100 rpm clockwise. Knowing that the angular velocity of arm AB is 50 rpm counterclockwise, determine the corresponding angular velocity of gear B.
Consider a magnet moving in a coil of N, turns. This system can be modelled as mass spring damper system. The damping coefficient consist of both mechanical and electromagnetic damping. How can I calculate the mechanical electromagnetic damping?
Determine a symbolic expression for the total thermal resistance of wall, including inside and outside convection effects for prescribed conditions.

A bullet is fired vertically at a latitude of 50 degrees N with a muzzle speed of 1000m/s. Neglecting air friction, determine the landing point of the bullet.
High school Yr 12 aeronautical Engineering Module - mechanics, PLease help- i seem to get the incorrect answer but didn't know where i have gone wrong?
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..
Describe the main kinds of social mechanisms that are used by people to communicate and collaborate.
Consider a supersonic wind tunnel with test section Mach number of 2 and fixed geometry diffuser designed to operate with minimum stagnation pressure losses (smallest diffuser area).
draw the shear and bending-moment diagrams for the beam and loading shown and determine the maximum normal stress due to bending.
Calculate the mass flow (in slugs/per second) that comes out the exit of the engine. The plane is at standard altitude 50,000 ft and velocity = 2200 ft/s. Would appreciate attack to problem.
the velocity of a lift increases uniformly from zero to its maximum value at mid-height (1.4m) in 7.5s and then decreases uniformly to zero in 7.5s. The peak power output is 6kW when the velocity is maximum, determine the maximum lift force provid..
