1. (a) A glued lap splice is to be made in a 10 × 20 mm rectangular member at α =20°, as shown in Fig.1. Assuming that, the shear strength of the glued joint controls the design, what axial force P is to be applied to the member to get separated to 2 parts? Assume the shear strength of the glued joint to be 10MPa.

(b) An exploded view of a bolted connection is as shown in Fig 2(b). The width of the plate is 60mm; their thicknesses are t1 =10mm. The snugly fitting bolt is 20mm in diameter. Calculate the maximum normal stress in the plates at the critical section due to an applied tensile force P=70 kN. For the same condition calculate the bearing and shear stresses in the bolt. t1 P/2

...separated into 3 distinct modes, general shear failure, local shear failure and punching shear. By determining the given mode of failure, it can be assessed its ultimate limit load and how a foundation might react when heavily loaded.
Vesic further adapted Terzaghi’s equation to measure the effect of soil compressibility. From measuring this additional effect, factors were added to the initial equation to provide a more sufficient equation....

SHEARSTRENGTH OF JOINT IN GRANITE
Introduction
Shearstrength is the extreme shearstrength where a material can support before rapture. Based on Lama and Vutukuri (1978)[1], it is one of the critical aspects used for designing purpose. There is no doubt that joint is a main factor that leads to failure in every rocks type including granite. In granite, shear...

...ANALYSIS
The vane shear apparatus makes use of the theory that the summation of the total shear stress is equal to the sum of the shear stress at failure along the cylindrical surface and the total shear stress on the top and the bottom of the surface of the cylinder. The various sizes of the vanes are accounted for by applying the multiplying factor. The value obtained from the medium sized vane is the value of the stress itself, and...

...Shear Stress
Forces parallel to the area resisting the force cause shearing stress. It differs to tensile and compressive stresses, which are caused by forces perpendicular to the area on which they act. Shearing stress is also known as tangential stress.
where V is the resultant shearing force which passes through the centroid of the area A being sheared.

The stress induced in a body, when subjected to two equal and opposite pulls, as a result of which there is an increase in length, is known as tensile stress. The ratio of increase in length to th original length is known as tensile strain. p p
