Meenach Corporation uses a job-order costing system with a single plantwide predetermined overhead rate based on direct labor-hours. The company based its predetermined overhead rate for the current year on 74,000 direct labor-hours, total fixed manufacturing overhead cost of $74,000, and a variable manufacturing overhead rate of $3.10 per direct labor-hour. Recently Job X387 was completed and required 210 direct labor-hours.

Required:

Calculate the amount of overhead applied to Job X387. (Do not round intermediate calculations.)

$ 861

Explanation:

We are given the  total fixed overhead from which we can determine the fixed overhead rate and then sum it up with variable overhead rate. The total overhead rate is multiplied with the number of direct labor hours to get the applied overhead.

Meenach Corporation

Total fixed manufacturing overhead cost  $74,000,

Predetermined  fixed overhead rate= Fixed manufacturing overhead cost  / No of direct labor Hours

Predetermined  fixed overhead rate=$74,000/74,000=$ 1

Variable manufacturing overhead rate of $3.10 per direct labor-hour

Total Overhead Rate= 1+3.10= $ 4.10

Job X387 required 210 direct labor-hours

Total applied Overhead to Job X387= $ 4.10 * 210= $ 861

sound is invisible, but sometimes we can feel it. when a kettle-drum is thumped with a stick that time the tight drum skin moving up and down very quickly for some time and then it pumped sound waves into the air. loudspeakers also work in a similar manner.

components of a speaker:

electromagnet

in order to translate an electrical signal into an audible sound, an electromagnet is used in looudspeakers

  suspension

suspension is used to   center the voice coil in the gap of the magnet and it exerts a restoring force to keep it there. suspension is used to limits the maximum mechanical excursion of the diaphragm and voice coil.

voice coil

voice coil is a coil of wire which is attached to the apex of a loudspeaker cone. it provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.

cone

in a   loudspeaker, a   thin, semi-rigid membrane attached to the voice coil, which moves in a magnetic gap due to which it vibrates   and produced sound. it is known as diaphragm and it can also be called a cone, though not all speaker diaphragms are cone-shaped.

surround

surround is also known as front suspension. surround is used to join the cone to the chassis. together with the suspension it controls the cone excursion, and it is also used to   determine how energy which is   travelling through the cone is absorbed, and how the speaker limits when it reaches the ends of its travel.

dustcap

dustcap is used to protect the voice coil from dust and dirt. it is a part of the cone.

how speaker work

the outer part of the cone is fastened to the outer part of the loudspeaker's circular metal rim. the inner part is fixed to   voice coil that sits just in front of a permanent magnet . when loudspeaker is hooked up to a stereo, electrical signals feed through the speaker cables into the coil. it will convert the coil into an electromagnet magnet . when electricity flows back and forth in the cables, the electromagnet either repels or attract the permanent magnet. this moves the coil back and forth, and it pull and push the loudspeaker cone. like a drum skin vibrating back and forth, the moving cone pumps sounds out into the air.in this way loudspeakers works.
