Around, cold-drawn 1045 steel rod has a mean strength s¯¯y=95.5 kpsi with a standard deviation of σˆsy=6.59 kpsi . the rod is to be subjected to a mean static axial load of p¯¯¯=65 kip with a standard deviation of σˆp=5.0 kip . assuming the strength and load have normal distributions, determine the reliability corresponding to the design factor of 1.4. also, determine the diameter for this design factor.

What precautions should you take to prevent injuries when dealing with heavy loads?

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false
