The torsional assembly consists of a solid bronze [G = 49 GPa] segment (1) with diameter d1 = 90 mm securely connected at flange B to solid stainless steel [G = 89 GPa] segments (2) and (3), with diameter d = 100 mm. The flange at B is secured by four bolts, with diameter db = 13 mm which are each located on a bolt circle with diameter dc = 100 mm. The allowable shear stress of the bolts is b = 80 MPa, and friction effects in the flange can be neglected for this analysis. Assume L1 = 500 mm, L2 = 750 mm, and L3 = 400 mm. Determine:
(a) the allowable torque TC that can be applied to the assembly at C without exceeding the capacity of the bolted flange connection.
(b) the maximum shear stress magnitude in bronze segment (1).
(c) the maximum shear stress magnitudes in stainless steel segments (2) and (3).
Footings for a structure are to be built beneath a basement slab on a clay soil at a depth of 20ft below present ground level. The groundwater table is 15 ft below the ground surface. The soil-void ratio is about 0.87.
A hawk flying at 2 m/s at an altitude of 45 m accidentally drops its prey. The parabolic trajectory of the falling prey is described by the equation below until it hits the ground, where y is its height above the ground and x is its horizontal dis..
The temperature of the poker at the third points of the poker using three elements of equal length. Use the finite element method. You may use Mathcad to solve this problem. If you do, please show all work and add comments to the Mathcad solution ..
You should provide the structural engineer with a formal typed report that will include all of your analyses and final size of the footing. You should also include all of your design assumptions in your report.
given: Vf=Vi + a t and Sf=Si + Vi t + 1/2 a t a= 27 ft/sec^2 accelerates from 10 mph to 93 mph in 4.5 seconds designers decided to modify the rise to become the tallest roller coaster in the world, find final velocity in mph if the drop height is ..
Determine the liquid detention time, loading rate, F/M ration (with an MLSS of 2350 mg/l), sludge age (with 5330 lb/day waste sludge Eff. SS= 20 mg/l. Will the sludge settle properly
What do you understand by the term durability? Compared to other considerations, how much importance should be given to durability in the design and construction of concrete structures?
To prevent this high compression load from buckling the copper pipe, a solid steel support of 2 1/2 inch diameter is placed inside the copper pipe. The copper pipe is 8.000 inches long. The steel support is 8.0001 inches (exactly 1 mil = 1/1000 in..
The height (in meters) of a projectile shot vertically upward from a point 2 m above ground level with an initial velocity of 24.5 m/s is h2+24.5t-4.9t^2 after t seconds. a) When does the projectile reach its maximum height? b) What is the maximum..
The "Shape Factor" of a cross-section of a beam is defined as the fully plastic strength divided by the force or moment causing first yield. Thus the Shape Factor for bending is Mp/My and similarly for shear, is Vp/Vy.
What is the concentration of tracer in the reactor 1 h after tracer addition is terminated? The reactor had an initial concentration of tracer of 1.0 mg/L when tracer addition commenced.
