A small 110-g particle is projected with a horizontal velocity of 2m/s into a the top A of the smooth circular guide (radius 250 mm)fixed in the vertical plane. Calculate the time rate ofchange dHB/dt of angular momentum about point B when theparticle passes the bottom of the guide at C.
What gas pressure will the experimenter measure inside the bulb, A glass bulb contains air at room temperature and at a pressure of 1 atmosphere. It is placed in a chamber filled with helium gas at 1 atmosphere and at room temperature
An air conditioner in the airport of Timbuktu runs a cooling system using R-410a with a high pressure of 1500 kPa and a low pressure of 200 kPa. It should cool the desert air at 45 degrees C down to 15 degrees C. Find the cycle COP. Will the syste..
the pin c will support a force of 24 knmagnitude.Based on this criterion, you are asked to determine the largest mass m that the frame can safely support.the diameter of pulley at d is given as 0.2 m.find maximum mass m that can be supported by fr..
A process with Gp= 2/(2s+1) and Gd=1/(2s+1) experiences a disturbance step change of magnitude 5. The SP remains constant. If a P-controller alone with Kc=1 is used and Ga=Gs=1, then what is the output variable, delta Y(t) versus time?
A tensile specimen of cartridge brass sheet has a cross section of 0.320 in. × 0.120 in. and a gage length of 2.00 in. Calculate the engineering strain that occurred during a test if the distance between gage markings is 2.35 in. after the test.
In flows past solid bodies, the force exerted on the body by the fluid motion depends upon the fluid velocity u, the density p, the viscosity
A 40 mm diameter hole is drilled 3 m deep into the steel shaft. When the two torque are applied, determine (a) the maximum shear stress in the shaft: and (b) the angle of rotation of the free end of the shaft. Use G= 83GPa for steel.
Beryllium has an HCP unit cell for which the ratio of the lattice parameters c/a is 1.568. If the radius of the Be atom is 0.1143 nm, (a) determine the unit cell volume, and (b) calculate the theoretical density of Be.
