During the time study of a task, a portion of the task was timed separately and found to average 0.08 min. This separately timed activity consisted of a 25in. reach (by a previously stationary hand) to an object in a fixed location, a grasp of a 3/4in. diameter rod (weight 1/2 lb) with some interference. These actions were followed by a 20 in. move to an approximate location, an exact positioning with heavy pressure required into a hole which could take the rod in either of two orientations, and a normal release. All of these activities could be performed by the preferred hand. The entire assembly task, of which the separately timed elements were only part, was timed to be 1.25min. What is the normal time for this assembly task based on MTM synthetic rating system

Laval produces lamps and home lighting fixtures. its most popular product is a brushed aluminum desk lamp. this lamp is made from components shaped in the fabricating department and assembled in the assembly department. information related to the 22,000 desk lamps produced annually follows.direct materials $280,000direct labor fabricating department (8,000 dlh × $24 per dlh) $192,000assembly department (16,600 dlh × $26 per dlh) $431,600machine hours fabricating department $15,200mhassembly department $20,850mhexpected overhead cost and related data for the two production departments follow.fabricating assemblydirect labor hours 150,000dlh 295,000dlhmachine hours 161,000mh 128,000mhoverhead cost $400,000 430,000required1. determine the plantwide overhead rate for laval using direct labor hours as a base.2. determine the total manufacturing cost per unit for the aluminum desk lamp using the plantwide overhead rate.3. compute departmental overhead rates based on machine hours in the fabricating department and direct labor hours in the assembly department.4. use departmental overhead rates from requirement 3 to determine the total manufacturing cost per unit for the aluminum desk lamps.
