The structure shown consists of two uniform legs, each having the same mass per unit length of 10.3 kg/m. The leg BC connects to the other leg via a pin-joint at B, such that free rotation at B is possible. If the smallest value of the angle 0 for which the structure will remain in static equilibrium is 58.7 degrees (i.e. slipping does not occur at either contact point A or C), calculate the coefficient of static friction, assuming the same value at both contact points A and C.

A pipe with a weight of 3.7 kg/m is attached to a wall such that all degrees of freedom are restraint. At the free end of the pipe a vertical load P=100 N pointing downwards is introduced with an excentricity of 100mm from the axis. The pipe has an length of 1m and is made of steel with the Young's modulus of 210 GPa and the Poisson ratio of 0.3125. The moment of inertia is l=19.7 cm“ whereas the polar moment of inertia J = 2 I. First, as part of the mechanical properties determine the Shear Modulus. Then determine the total vertical deflection at the point where the vertical load is being introduced. Note: Use the principal of superposition. ANSWERS: Shear Modulus %3D [MPa] Vertical deflection due to weight only [mm] Vertical deflection due to End-Load (excentricity NOT considered) [mm] Vertical deflection due to excentricity of the End-Load only [mm] Total vertical deflection [mm]
