The bimetallic strip material of Example 8.1 is to be used in an on-off-temperature-control device, which will operate at a nominal temperature of 200?F. Calculate the deflection at the end of a 4-in strip for deviations of ±1 and 2?F from the nominal temperature.
Example 8.1
A bimetallic strip is constructed of strips of yellow brass and Invar bonded together at 30?C. Each has a thickness of 0.3 mm. Calculate the radius of curvature when a 6.0-cm strip is subjected to a temperature of 100?C.
identical bricks 0.1m wide and weighting 2kg are placed on a plate assume the plate has neligible weight. calculate the
An adiabatic and reversible air compressor takes air in at 15 psia, 560 R. The air exits at 90 psia at the rate of 0.8 lbm/s. Determine the minimum compressor work input and repeat for an inlet at 530 R instead. Why is the work less for a lower in..
Having identified the microorganism involved the biodegradation and discovered that its mode of action is zero-order reaction with a reaction rate of 20 mg/kg-year, you concluded that in one more year the site will be free of all contamination.
Describe the overall process (i.e., steps) that you would apply in the design and development of a SOS configuration. What tools/techniques would you apply as an aid in the accomplishment of such?
A bar having a square cross section of 30 mm by 30 mm is 2 m long and is held upward. If it has a mass of 5 kg>m, determine the largest angle θ, measured from the vertical, at which it can be supported before it is subjected to a tensile stress al..
Calculate the moments MA and MB about point D for the forces applied at pointsA and B. Then, determine the resulting couple moment MR. Assume that a positive moment produces a counterclockwise rotation whereas a negative moment produces a clockwise r..
Assuming the kinetic and potential energy effects to be negligible, determine D) the isentropic turbine efficiency E) the entropy at the exit of the turbine, in kJ/kg K F) the rate of entropy production within the turbine
suppose you apply a force of 14.4 N to a spring and it stretches 2.4 cm. what is the spring constant?
Explain the purpose of the first bit in terms of generating orthogonal signals. (b) Assume that the mod-2 sum of each pair of rows of Hb is another row of Hb for any given integer b ≥ 1. Use this to prove the same result for Hb+1
What are the merits and demerits of concrete in construction industry?
A system consists of a gas confined between a cylinder and piston such that work and heat may cross the boundary. What type of system is that. What type of system is a free body as used in mechanics or civil engineering.
An airport runway has a capacity of 60 operations (ie landing and take-offs) per hour. In a particular hour, there are 30 landings evenly spaced over the hour.
