Southern Rim Parts estimates its manufacturing overhead to be $396,000 and its direct labor costs to be $990,000 for year 1. The first three jobs that Southern Rim worked on had actual direct labor costs of $58,000 for Job 301, $83,000 for Job 302, and $140,000 for Job 303. For the year, actual manufacturing overhead was $434,000 and total direct labor cost was $841,000. Manufacturing overhead is applied to jobs on the basis of direct labor costs using predetermined rates. Overhead applied in each of the inventory accounts is as follows: Work-in-process inventory $ 33,640 Finished goods inventory 84,100 Cost of goods sold 218,660 Required: Prepare an entry to prorate the under- or overapplied overhead. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field.)

To record the prorated under-applied overhead cost.

Explanation:

a) Data and Calculations:

Estimated manufacturing overhead = $396,000

Estimated direct labor costs = $990,000

Actual manufacturing overhead = $434,000

Actual direct labor costs =  $841,000

Predetermined overhead rate = estimated overhead/estimated direct labor costs = $396,000/$990,000 = $0.40 per DL

Applied overhead:

Work-in-process inventory $ 33,640

Finished goods inventory 84,100

Cost of goods sold 218,660

Total overhead applied = $336,400

Underapplied overhead = $97,600 ($434,000 - $336,400)

Prorating the underapplied overhead to:

Work-in-process inventory $33,640/$336,400 * $97,600 = $9,760

Finished goods inventory 84,100/$336,400 * $97,600 = $24,400

Cost of goods sold 218,660/$336,400 * $97,600 = $63,440

Total underapplied overhead = $97,600

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.
