I wouldnât say customer service is a standalone skill or trait. But, when companies talk about important customer service qualities or skills, empathy comes up a lot. Previous articles have considered it as one of the key qualities in customer service.
The values in Table 2 show the upper limits of forces for vertical pushing and pulling. Examples of the use of vertical force are operating controls and hand tools. Such activities tend to be of a repetitive nature and physically more demanding than occasional pushing or pulling. Therefore, these tasks should be designed for considerably lower force requirements than those shown in Table 2.
The weight of an average adult exerts a force of about 550 - 800 N. Bench pressing 100 pounds (45 kg) takes a little under 450 N of force. A newton is not much force, so it is common to see forces expressed in kilonewtons, or kN, where 1 kN = 1000 N. For example, the tractive effort of a Class Y steam train and the thrust of a an F100 fighter jet are both around 130 kN.
