Example 2: Simple shear A thin steel plate is deformed in shear as shown Determine the 2D stress and strain fields 0.015 cm 20 cm
A support fitting is machined from 7075- T651 aluminum alloy plate, and is attached to a beam using 6 steel bolts as shown. The external loads are applied through a two-lug clevis configuration, and it is assumed that that each lug supports 60% of the applied external load. A fitting factor of 1.15 is to be applied to the lugs, and the bolts have a maximum allowable shear load of 1900 lbf. All dimensions are in inches. (a) Find the...
(2) For the shown hollow steel shaft, it is required 1.00 m to determine the maximum torque T that can be resisted by the shaft so that: a) The maximum shear stress does not exceed 60 MPа. т b) The maximum angle of twist does not exceed 3° Given: The shear modulus, G = 70 GPa 30 mm 25 mm
The joint shown in Figure 1 is made from steel Grade 350 (AS/NZS 3678). Four bolts are used. Diameters of all holes are 5 mm. Note that the middle hole on both Plates A is just a hole with no bolt. The shear design capacity (reduced nominal capacity) of the bolts in single shear is 10 kN. Dimensions given below are in mm. Determinre the maximum tension design force: a) * N2PlatesA that the double plate A can support. b)...
Problem 1: Shear Lag Factor & Effective Areas For the steel tension members and corresponding connections shown below, determine the effective area. Note that the abbreviation PL indicates a steel plate with naming convention: thickness x width. Assume standard diameter holes, where applicable a) For each case, compute or determine the shear lag factor, the net area, and the effective area. Tabulate your final answers lowest values? What do these values mean in terms of the stresses at the connection?...
1) For the loading of the beam shown below, determine the maximum normal and shear stress at the wall if Kt for bending is 2.7 and K, for torsion is 2.3 If we use a steel with an Sy 600 MPa, what is the "safety factor" if we only consider the maximum normal stress? Notice the bending moment, start with a cross product to determine the moment at the wall. The vector R-[0.25,0,0.3] in meters 200 mm 25-mm-dia. round rod...
i need clear and right solution pleaee. pleaes A steel plate of (0.5 in thickness) shown in the figure was fixed by four bolts of (0.5*13-UNC grade 4) to the vertical steel column of (0.6 in thickness) as shown in figure below. An inclined eccentric force F of 10 kips was subjected to the plate at point A. Calculate: (a) The maximum stress in the rivets. (b) Check the safety factor if the plate and wall have a tensile strength...
