tension in the screw exceeding the tensile strength and break-ing of the screw. On the other hand, if the screw is completely dry of lubricant the clamping force might be too small to withstand the forces for which the joint is designed, with the risk that the screw becomes loose. Table 1. Friction in threads of different material.

Poor or Improper Maintenance. CNC machines need to be carefully cleaned and lubricated on a regular basis — otherwise, problems can begin to arise. A lack of cleaning could lead to a buildup of dirt and debris. This might seem to be purely a hygiene issue, but it can have real implications in the machine's output.

Tension is the force that actually holds an assembly together. Put another way: A bolt can stretch similar to a spring, as it becomes tightened once all the parts of the assembly are brought together. The higher the torque applied to the fastener, the more tension is created as the bolt stretches.

To simply convert from any unit into pascals, for example, from 5 bar, just multiply by the conversion value in the right column in the table below. 5 bar * 100000 [ (Pa) / (bar) ] = 500000 Pa. To convert from Pa into units in the left column divide by the value in the right column or, multiply by the reciprocal, 1/x.

The dimensions for surface tension are expressed as force per unit length or energy per unit area. The surface tension of water is 72 dynes/cm at 25°C indicating that it would take a force of 72 dynes to break a surface film of water 1 cm in length [11]. Surface tension varies between liquids and is affected by temperature.

One of the most important things to remember about sling tension is that the lower the angle between the load and the sling, the higher the tension on the sling. Angles also increase the tension on hardware. Hardware's rated capacity decreases when it is pulled from any direction other than vertical.
