The bevel protractor is used to establish and test angles to very close tolerances. It reads to 5 arcminutes (5′ or 1 / 12 °) and can measure angles from 0° to 450°. The bevel protractor consists of a beam, a graduated dial, and a blade which is connected to a swivel plate (with Vernier scale) by a thumb nut and clamp.

Dial test indicator. A dial test indicator, also known as a lever arm test indicator or finger indicator, has a smaller measuring range than a standard dial indicator. A test indicator measures the deflection of the arm, the probe does not retract but swings in an arc around its hinge point.
If the principle of virtual work for applied forces is used on individual particles of a rigid body, the principle can be generalized for a rigid body: When a rigid body that is in equilibrium is subject to virtual compatible displacements, the total virtual work of all external forces is zero; and conversely, if the total virtual work of all ...
The head usually has one face at 90° to the ruler, and another face at 45° to the ruler. Originally designed for machinists, the tool is also commonly used in woodworking. They can also be purchased with centre finder heads and protractor heads and often incorporate a spirit level. [8] [7] Cylindrical square, or cylinder square
The completed drawing was then cut free. [3]: 1-2 Paper could also be secured to the drawing board with drawing pins [4] or even C-clamps. More recent practice is to use self-adhesive drafting tape to secure paper to the board, including the sophisticated use of individualized adhesive dots from a dispensing roll. Some drawing boards are ...
