shown in Figure 2. Two circular disks A and B are welded to the ends of both bars. The disks lie in planes disks A and B subjecting the bars to torsion. If the allowable maximum shear stress is 35 MPa and the allowable rate of twist is 3°/m for both bars, determine the smallest outer diameter (D, and Di) of both bars. The shear modulus of elasticity is 39 GPa to the axes of the bars. Forces 15 kN...

P6.010 The mechanism shown in the figure is in equilibrium for an applied load of 25 kN. Specifications for the mechanism limit the shear stress in the steel [G82 Ga] shaft BC to 58 MPa, the shear stress in bolt A to 9u MPa, and the vertical defection of joint D to maximum value of 40 mm. Assume that the bearings allow the shaft to rotate freely. Using L-1.200 mm, -115 mm, and b-225 mm, calculate (a) the minimum diameter...

Part 1
A cantilever flexural member is fabricated by bolting two
identical cold-rolled steel channels back-to-back, as shown. The
cantilever beam has a span of L = 1300 mm and supports a
concentrated load of P = 500 N. The cross-sectional
dimensions of the built-up shape are shown, where d = 40
mm, w = 65 mm, and t = 3 mm. The effect of the
rounded corners can be neglected in determining the section
properties for the built-up shape....

1.8-18 A removable sign post on a hurricane evacu- ute (see figure part a) consists of an upper pole with a slotted base plate bolted to a short post anchored in the ground. The lower post is capped with a separate conventional base plate having four holes of diameter d, The upper base plate has slots at locations 1 to 4 and is bolted to the lower base plate at these four points (see figure part b). Each of the...

Diameter of pin 2 mm. All pins are in single shear.
Question 1: A light plane structure is supported by a roller at A and a pin at D and is subjected to a load of Pat F as shown in the figure. All the members have rectangular cross section with height 5 mm and thickness 1 mm. Tensile/Compressive strength of the members = 80 MPa, Shear strength of the pin = 50 MPa. Consider an appropriate factor of safety....
