Q.1) Block A is connected to block B by a pulley
system as shown. The weights of blocks A and B
are 100 lbs and 70 lbs, respectively. Assume
negligible friction between the rope and all pulleys
as well as between block B and the incline and
neglect the mass of all pulleys and cables.
Determine the angle 0 required to keep the system
in equilibrium. (At least two FBDs must be drawn
for full credit)

The stepped rod in sketch is subjected to a tensile
force that varies between 4000 and 7000 lb. The
rod has a machined surface finish everywhere except
the shoulder area,
where a grinding operation has
been performed to improve the fatigue resistance
of the rod. Using a 99% probability of survival,
determine the safety factor for infinite life if
the rod is made of AISI 1080 steel, quenched
and tempered at 800°c Use the Goodman line.
Does the part fail at the fillet? Explain

- Large wind turbines with a power capacity of 8 MW and blade span diameters of over 160 m areavailable for electric power generation. Consider a wind turbine with a blade span diameter of 120m installed at a site subjected to steady winds at 8.25 m/s. Taking the overall efficiency of thewind turbine to be 33 percent and the air density to be 1.25 kg/m3, determine the electric powergenerated by this wind turbine. Also, assuming steady winds of 8.25 m/s during a 24-h period,determine the amount of electric energy and the revenue generated per day for a unit price of$0.08/kWh for electricity.arrow_forwardThe basic barometer can be used to measure the height of a building.
