In order to ascertain the loss due to idle machinery during periods of slack production it is necessary to keep a record of the hours each machine is idle and extend the total by the hourly machine rate, which includes such elements of indirect expense as are directly chargeable to the machine. Factory superintendents know that there is a point below which they cannot reduce their operating expenses. Even when a plant is idle for a period certain expenses continue to run on. Reference to the following example will illustrate the method of calculation. Example.--What is the loss due to idle machinery for the month of January, 1917, from the following report? The hourly rate for all factory expense directly chargeable to each of the seven machines above mentioned is as follows: Problem 44 From the data given in Exhibit 32, make a calculation of tbe loss due to idle machinery in the sensitive drill press department of a factory.
