Answer to Question #249775 in Mechanical Engineering for roger

Question

A CEO of a well-known television show wants to build a new rectangular shaped acting stage. The width, thickness and length of the stage are 3 m, 0.2 m and 5 m, respectively. Both ends of the stage must be fixed. The stage should carry a musical instrument, and air conditioner of a total mass of 1500 kg and 800 kg at 1 m, and 2 m from the left end support. Such equipment acts as a concentrated loads on the stage that has a distributed load of 500 kg/m. The Young’s modulus of the material is 200 GPa. 1.1. Use the engineering sketch to illustrate the structure of the stage and calculate the transverse vibration frequency of the stage. (18) 1.2. Determine the amount of rection forces on the stage supports. 

Answer 1

To build or not to build, that is the question. Theater productions have the ability to enthrall audiences…to take them out of reality and transport them to a different era, to a whole new world. Now, this is largely due to the skill of the actors onstage, but the other major component is the set design. A stage production with an amazing set has the power to take an audience member completely outside of themselves and put them into the story unfolding before their eyes.

DESIGN

Before you can even begin to construct a theater set, a lot of behind the scenes design work must be completed. Every production is different in terms of its setting and time period, so the set needs to properly reflect the production. It’s an important job, too: the set is usually the first part of the show that an audience sees. Set designers will typically begin researching the play and its setting to get inspiration for walls, color schemes and different furniture items or props that should be present.

The designer must also keep the whole play in mind–including act and scene changes–when they’re drawing up a plan for the set. Perhaps there’s a large piece they really want to use, but the stage crew can’t move it quickly enough between scenes. Some productions elect to use bulkier sets as the backdrop for the entirety of the show, while others will change set pieces between every scene.
