Sampling procedures ways evacuated container method is as follows: 1) Evacuation sample container to a pressure of 1 mm Hg or below. (Use cylinder having facilities evacuation and tested in a vacuum). Before use, the vacuum can be tested with a vacuum gage. Note: As an alternative to cylinder evacuation, the cylinder can be charged up to a positive pressure ...

Pada bantalan ini terjadi gesekan luncur antara poros dan bantalan karena permukaan poros ditumpu oleh permukaan bantalan dengan perantara lapisan pelumas. Bantalan luncur mampu menumpu poros berputaran tinggi dengan beban yang besar. Dengan konstruksi yang sederhana maka bantalan ini mudah untuk dibongkar pasang. Akibat adanya gesekan pada bantalan dengan poros maka akan memerlukan momen awal yang besar untuk memutar poros. ...

In discussing the tensile strength can not be separated from the stress and strain. Both of these properties were measured during a tensile or pressure. In the pull, strain is the length of the material, while the press is pemendekkan of material are pressed. Results of the stress and strain if the share will yield a Young’s modulus (E). Young ...

The development of sensors and transducers very quickly according to the progress of automation technology, increasingly complex an automated system is built, the more types of sensors are used. Robotics is as an example of a complex automation system, sensors are used here can be categorized into two types of sensors, namely: a. Internal sensor, the sensor mounted on the ...

A number of forces acting on a structure can be reduced to a single resultant force, then this concept can assist in simplifying problem. Calculate the resultant force depends on the amount and direction of the gayagaya. Some way or method to calculate the resultant force, namely: 1. Method force vector addition and subtraction. 2. The method of triangular and ...
