The hand brace shown in the figure is used to pply a torque of \( 3 \mathrm{Nm} \) and a thrust of \( 225 \mathrm{~N} \) to the bit in boring a ble in a wood. a) Make a three dimensional abstract drawing of the brace and calculate and show all the reactions. b) The drill used has a shank diameter of \( 6 \mathrm{~mm} \) where it projects from the chuck at section B-B. If the distance from \( B-B \) to the surface of the wood is \( 80 \mathrm{~mm} \), find the largest of the normal stresses at this section when the plane of the brace is horizontal. Calculate the shear stress at the same point.
