Sir Edward decided to replicate the experiment of Torricelli (see diagram). He immersed a tube with a diameter of 3mm in Hg at temperature of 68°F. What is the height that the column generated in mm? h 51°

The following stress condition is applied to a cubic material.Normal stress in the x direction is 15 Mpa, normal stress in the z direction is -7 Mpa and the shear stress in the x-z plane is 59 Mpa.(a) Write the stress tensor(b) Find the maximum normal stress(c) Find the angle with respect to the x- axis at which the maximum normal stress is applied(d) Find the maximum shear stress(e) Determine the angle with respect to the x-axis at which the maximum shear stress is experienced

Take point H in the = 1. (Outcome 2) A submarine is 30 m below the surface of the ocean. (You may = 1.6 figure to be at the 30 m depth.) The circular hatch is hinged at point H and has diameter D Find the net m. The hatch is inclined at an angle of 30° to the horizontal as shown in the figure. force required to open the hatch when applied as shown in the figure, perpendicular to the hatch. The pressure inside the submarine is equal to the atmospheric pressure and the density of sea water is 1030 kg/m³. Note that the area moment of inertia for a circle about a diameter is equal to where R is the radius of the circle. (Hint: Do not try to solve this problem by solving for vertical and horizontal forces separately!) 30 H F D= 1.6 m
