A first class lever, in static equilibrium, has a 50lb resistance force and 15lb effort force. The lever's effort force is located 4 ft from the fulcrum.3. Using static equilibrium calculations, calculate the length from the fulcrum to the resistance force.
Friction between the piston and the cylinder wall can be neglected. For the air, determine the initial and final pressures, in kPa, and the work, in kJ.
You have a 120 Ω quarter bridge 2 wire set up with Sg=2.10 and an unknown lead wire resistance. A 59880Ω calibration resistor is switched in parallel to the gage only and a recording instrument is set to give a -100 mm deflection for this calibrat..
Neglecting the mass of the rod and the effect of friction, determine the radial and transverse components of the velocity of the collar when r = 0.5 m.
At a given instant in time, flywheel OA is caused to rotate with angular velocity of w=2rad/sec and angular acceleration of alpha=6rad/s2. determine the angular velocity of links AB and BC at this instant in time. AB=.5m, BC=.4m, OA=.3m
In the an ideal turbo jet, the engine is designed such that the turbine work is divided equally between the compressor and the propeller. The gas from the turbine discharges to a nozzle for additional thrust.
Calculate the average square distance between the particles and plot its ratio to the time step . This is the diffusion/dispersion coefficient.
calculate the enthalpy change of the universe during the process. Cp=Cv = 4.18 kj/kgK
Determine the outlet temperature of the hot fluid.
a turbofan jet engine has a large fan that sucks in air. some of this air enters a set of compressors is mixed with
Find a cylindrical container that is large enough that it takes at least one minute to drain (you may have to create an opening at or near the bottom that gives the right behavior.
At what location S will the combined moment of the weights of the man and platform about point B be zero?
Compute the theoretical density of CaF2, which has the fluorite structure. Ionic radii of Ca2+ and F- are 0.100 nm and 0.133 nm respectively.
