The smallest diameter will be a diagonal between corners on the cube.
The highest and lowest point are directly above each other in the plan so a line connecting them will be true length in the end view.
2013 A-2
Distance between the centres is (radius of pin )+ (radius of ball)
Use a locus to find the centre of the cylinder

Look at the red lines to see how to locate the points on the projection, continue like this to complete
Take length from RHS view and project perpendicular by this distance on LHS view to find diagonal
2012 A-2
For true shape, create an auxiliary view with sign as a line (true length top to bottom)
Rotate and project back to plan to draw true shape

Horizontal lines go to vanishing points (VP)
Sloping surfaces in logo go to aux vanishing point (AVP) on ground
Sloping roof lines go to aux vanishing point near PP line
