The demise of this particular 1971 Lotus Seven S4 occurred as a result of a fuel leak in the engine bay. Despite turning off the engine and ignition, the fire consumed the bonnet, both wings, and the majority of the cockpit moldings, as well as the steering column, windscreen, seats, radiator, carburetor, and all gauges and switches. Once the decision to restore the car was taken, the first step was to completely strip everything down to the bare chassis.

Removal of the remains of the body

The only remaining parts of the fiberglass bodywork were a portion of the main tub section and part of the seat areas ( [link] - [link] ). One consequence of the fire was that the true color of the car was revealed, as the paint had pealed off in several areas. As with some of its other models, Lotus had experimented with self-colored fiberglass composites, in which the color was incorporated into the gel coat. Instead of the traditional British racing green, the original fiberglass had been bright orangish red (see [link] ), which was one of the original colors, including: white, red, yellow, pale blue, and the very seventies lime green. According to Lotus records this car was originally red. At this point it is intended that the restored car be returned to the original bright red as a homage to the cars original configuration.

Prior to removal of the remains of the body from the chassis, the fire destroyed battery had to be removed, along with residual battery cables. The battery tray is bolted through the boot floor, and was considerably corroded ( [link] ) as a consequence of the damage to the battery ( [link] ). Removal of the spare wheel is accomplished by unscrewing the two long bolts that pass through the rear body into the threads on the spare wheel bracket ( [link] ).

The body remains were removed from the chassis by removal of the mounting bolts. Detachment of the fuel filler hose was also required in order to free the fiberglass from the chassis. Once separated, the rear light clusters were unscrewed and found to be intact ( [link] ), although the wiring will need replacing.

The fire had consumed the copper core of the radiator, and a whole new radiator will be needed. The radiator support brackets were removed ( [link] ).

The rubber brake lines to the front brake calipers had been destroyed in the fire, and the plastic reservoirs of the brake and clutch master cylinders were badly damaged. They were removed from the metal bulkhead, as was the pedal unit ( [link] ), and the remains of the handbrake.

Questions & Answers

A golfer on a fairway is 70 m away from the green, which sits below the level of the fairway by 20 m. If the golfer hits the ball at an angle of 40° with an initial speed of 20 m/s, how close to the green does she come?

Chemistry is a branch of science that deals with the study of matter,it composition,it structure and the changes it undergoes

chemistry could also be understood like the sexual attraction/repulsion of the male and female elements. the reaction varies depending on the energy differences of each given gender. + masculine -female.

can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Joseph Reply
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing
