A 300kg compressor is placed at the end of a cantilever beam of length 1.8 m made of a material with an elastic modulus of 200*10^9 N/m^2. The beam has a moment of inertia of 1.8*10^-5 m^4. When the compressor operated at 1000 rpm, it has an amplitude of 1.2mm. What is the compressor's steady state response when a 30kg absorber with a stiffness of 1.3*10^5 N/m is added to the end of the beam? Please determine how to change the absorber to minimize the response of the beam.
If a person and a wheelchair have a mombined weight of 185 lb how much ideal effort force is required to travel up the ramp? Can you just explain to me what equation I need for this?
Calculating the mechanical properties of unidirectionally reinforced composites
A circular shaft is subjected to a torque Ta and a bending moment Ma. Assuming that the diameter of the shaft is d, determine the expressions for the principal stresses and maximum shear stress in terms of Ma, Ta and d.
The Brayton cycle shown in figure 6.41 operates using CO2 as a working fluid with compressor and turbine isentropic efficiencies of 1.0. Calculate the thermal efficiency of this cycle when the working fluid is modeled.
