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.

Two strips of metal are riveted together at their ends by four rivets, each of diameter 6mm. What is the maximum tension that can be exterted by the riveted strip if the shearing stress on the rivet is not to exceed 6.9 xx 10^(7) Pa ? Assume that each rivet is to carry one quarter of the load .

Two strips of metal are riveted together at their ends by four rivets, each of diameter 6 mm. Assume that each rivet is to carry one quarter of the load. If the shearing stress on the rivet is not to exceed 6.9xx10^7Pa , the maximum tension that can be exerted by the riveted strip is

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 glass U-tube is such that the diameter of one limb is 3.0mm and that of the other is 6.0mm. The tube is inverted vertically with the open ends below the surface of water in a beaker. What is the difference between the height to which water rises in the two limbs? Surface tension of water is 0.07Nm^(-1) . Assume that the angle of contact between water and glass is 0^(@) .

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 straight metallic strips each of thickness t and length l are rivetted together. Their coefficients of linear expansions are alpha_(1) "and" alpha_(2) . If they are heated through temperature DeltaT , the bimetallic strip will bend to form an arc of radius

Two narrow bores of diameters 3.0mm and 6.0 mm are joined together to form a U-shaped tube open at both ends. If th U-tube contains water, what is the difference in its levels in the two limbs of the tube? Surface tension of water at the temperature of the experiment is 7.3xx10^(-2)Nm^(-1) . Take the angle of contact to be zero. and density of water to be 1.0xx10^(3)kg//m^(3) . (g=9.8 ms^(-2))

A copper wire of diameter 1.0 mm carries a current of 0.2 A. Copper has 8.4xx10^(28) atoms per cubic metre. Find the drift velocity of electrons, assuming that one charge carrier of 1.6xx10^(-19) C is associated with each atom of the copper.

Two water taps together can fill a tank in 9(3)/(8) hours.The tap of larger diameter takes 10 hours less than the smaller one to fill the tank separately.Find the time in which each tap can separately fill the tank.
