Two metal plates are held together by two rivets width radii of 0.2cm. If the maximum shear stress a single rivet can withstand is `5 xx 10^(8) Nm^(-2)`, how much force must be applied parallel to the plates to shear off both the rivets?

Two long metallic strips are joined together by two rivets each of radius 2 mm . Each rivet can withstand a maximum shearing stress of 1.5 xx 10^(9) N//m^(2) . Assuming that each rivet shares the stretching load equally, the maximum tensile force the strip can exert without rupture is

A drop of water placed between two parallel glass plates which are then pressed together unil the water film is 0.01 cm thick. If the area of water in contact with either plate is 10 cm^2 , then the force due to surface tension drawing the plates together is (S.T. of water is 75 dyne/ cm)

Calculate the force F needed to punch at 1.46 cm diameter hole in a steel plate 1.27 cm thick fig. The ultimates shear stress of steel is 3.45 xx 10^(8)Nm^(-2) .

Two large, thin metal plates are parallel and close to each other. On their inner faces, the plates have surface charge densities of opposite signs and magnitude 17.0xx10^(-22)Cm^(-2) . What is the electric field a. in the outer region of the first and the second plates? b. between the plates?

Two metaliic strips of different metals are riveted together to form a composite metallic strip of thickness 0.1 cm. If the strip is heated to 100^(@)C , what will be the radius of curvature of the strip? Given, the values of alpha of the two metals are 18 times 10^(-6@)C^(-1) " and " 12 times 10^(-6@)C^(-1) .

Two strips of metal are riveted together at their ends by four rivets, each of diameter 6.0 mm. What is the maximum tension that can be exerted by the riveted strip if the shearing stress on the rivet is not to exceed 2.3 times 10^9 Pa ? Assume that each rivet is to carry one quarter of the load.
