Estimate the natural frequency of the cantilever in Problem 29.24.
Problem 29.24
The atomic-force microscope probe shown in Fig. 29.31 has a stainless steel cantilever that is 450 μ m × 40 μ m × 2 μ m. Using equations from solid mechanics, estimate the stiffness of the cantilever, and the force required to deflect the end of the cantilever by 1 μ m.
Determine the total entropy change for the mixing process per unit mass of mixture.
How large must the sample be if we wish to be at least 95% confident that the error in estimating p is less than 0.02, regardless of the true value of p?
It now expands in a reversible polytropic process with exponent n = 1.5 through a volume ratio of 10:1. Show this process on P-v and T-s diagrams, and calculate the work and heat transfer for the process.
Moisture in the hot drying air condensing on the cooler grain near the plenum of the bin (Hint: The vapor in the ambient will condense out if the temperature of a surface is lower than the incoming air dew-point temperature).
Given: acceration = -k*sqrt(v) and k is a cosntant when x=0, v=81 m/s, t=0 when x=18 m, v=436 m/s determine: a) velocity of particle when x=20 m b) the time required for the particle to come to rest
A 200 pound man stands at the end of a 16 foot diving board (point C) with a pin at (A) and a roller located 6.695 ft away from A at point (B). The hollow diving board is made of aluminum
a prismatic bar AB of length L, cross section A, modulus of elasticity E, and weight W hangs vertical under its own weight. if the bar is a riser pipe hanging from a drill rig at sea, what is the total elongation of the pipe
You are provided with a brittle material whose ultimate tensile strength is 25% of its ultimate compressive strength. Plot the failure loci for each of the brittle failure criteria. For example, you may want to to either
Calculate the air mass flow rate in the shaft; the rate at which moisture is evaporated into the airstream and the rate at which heat is added to the shaft.
A 0.20 kg stone attached to a 0.8 m long string is rotated in a horizontal plane. The string makes an angle of 25° with the horizontal. Determine the speed of the stone.
Find the probability that in a sample of 100 bulbs, (a) 0 bulbs will be defective (b) 1 bulbs will be defective (c) 2 bulbs will be defective (d) 3 bulbs will be defective (e) 4 bulbs will be defective (f) 5 bulbs will be defective
