After a period of use, one of the blades of a shredder has been worn to the shape shown and is of mass 0.18 kg. Knowing that the mass moments of inertia of the blade with respect to the A' and BB' axes are 0.. m2 and 0.680 g . m2 , respectively, determine
(a) the location of the centroidal axis GG',
(b) the radius of gyration with respect to axis GG'.
Describe the physical properties of water that are relevant to its critical roles in plant physiology.
one pound of silver at 5000f is plunged into four pounds of water at 600f in a manner such that no wa-ter is
The spool has a mass of 50 kg and a radius of gyration of kO = 0.280 m. If the 20-kg block A is released from rest, determine the distance the block must fall in order for the spool to have an angular velocity v = 5 rad>s. Also, what is the tension i..
You are considering two different diffusion processes involving Carbon into FCC iron. The first process is carried out at 900 oC for 3 hours and produces a carbon concentration of 0.20 wt% at a depth of 2 mm. At what depth would this concentration oc..
Double-pipe heat exchanger. This type of heat exchanger is composed of concentric pipes, with hot water flowing in the inner pipe while cold water flows in the annulus between the inner pipe wall and outer pipe wall.
Niobium forms a substitution solid solution with vanadium. Compute the number of niobium atoms per cubic centimetre for a niobium–vanadium alloy that contains 27 wt% Nb and 73 wt% V. The densities of pure niobium and vanadium are 8.57 and 6.10 g/cm3,..
air enters a converging-diverging nozzle of a supersonic wind tunnel at 1 mpa and 37 ordmc with a low velocity. the
The distance from the centre of rotation to the centre of the mass is 1.5 m and the diameter of the wire is 2 mm. If the ultimate tensile strength of the steel is 500 MPa, determine the rotational speed at which the wire will break.
Air undergoes two processes in series: Process 1-2: Polytropic compression, with n = 1.3, from P1 = 100 kPa, V1 = 0.04 m3/kg to V2 = 0.02 m3/kg Process 2-3: Constant pressure process to V3 = V1 Sketch the cycle on a P-V diagram and determine the work..
to understand the physics of the o-ring we may need to start formulating the problem in a static equilibrium condition.
