Acantilever beam has a load p applied to the free end. the maximum stress in the beam can be determined using equation (1) 6pl (1) отах bh2 the elastic modulus of the beam is known to be e = 70 [gpa], the length of the beam is known to be 1.2 [m] and the width of the beam is known to be 0.05 [m]. calculate the maximum stress in the beam and the corresponding uncertainty at 95% probability given the measurements and associated uncertainties for the load p and the thickness h shown below load: p 700 n, bp = 7.23 n, sp4.36 n, n 8 thickness h 0.02 m, br = 0.22 mm n 11 = 1.11 mm

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis
