Answer to Question #318239 in Mechanical Engineering for govind

Question

A cube (40 mm) is resting on ground and all vertical faces are equally inclined to the vertical plane. A sectional plane, inclined to horizontal plane and perpendicular to the vertical plane is cutting the cube to get a regular hexagonal cutting shape (true shape) on cube. Find the angle of the cutting plane to the horizontal and draw the projections of cube (front view and sectional top view). Develop the true shape of the cutting surface.

Answer 1

True Shape: The projection of a section on a plane parallel to the section plane will show the true shape of the section.

When the section plane is parallel the H.P. or the ground, the true shape of the section will be seen in sectional top view.
