Using a finite-difference method with a space increment of 4mm, estimate the temperature distribution within the fin. Is the assumption of one-dimensional heat transfer reasonable for this fin?
The composite beam is made of A-36 steel (A) bonded to C83400 red brass (B) and has the cross section shown. If it is subjected to a moment of M=6.5 kN*m, determine the maximum stress in the brass and steel.
The International Space Station orbits the Earth at an average altitude of 362 km. Assume that its orbit is circular, and calculate its orbital speed. The Earth's mass is 5.97×1024 kg and its radius is 6.38×106 m.
Thirty percent of diabetic patients admitted to a hospital have kidney problems. A sample of 10 hospital admissions of diabetics is drawn. The value x the number of people having kidney problems is reported.
A mass of 10 kg is vertically accelerated from rest to 10 m/s through a height of 100 m. The internal energy of the mass increases by 100 J/kg. Determine the change in total energy (J).
If you know that 48% of children born are male, what is the probability of having 2 girls and one boy in a family of 3 children. Order is unimportant, (but you want to use binomial distributions or a probability tree.)
