Engineering initiation - Research Paper ExampleThe ease of accommodating the power source can also be increased by cargonfully selecting a location for installing the source. The largest dimensions be of Honda GX 35 i.e. 7.8 ? 9.8 ? 12.7. The calculations of the resistive forces are very simple because the only resistive force to the motion of the bicycle is the frictional force (Wormell). The frictional force can be coupled with the gravitational force while the bicycle is travelling on an inclined surface. For an inclined surface we can assume an angle of 4-8 degrees at the tourist resort at roads where the bike can travel. We impart do the calculations for 8o inclined plane. Pr = s FN + W intrude ? Where Pr is the summate resistive force s is the coefficient of friction taken as 0.005 for bicycle tyres FN is the dominion force equal to the weight (mg) of the bicycle and the device driver W is the combined weight of the bicycle and the driver = mg (mass ? gravitational accele ration) ? is the angle of inclination of the road = 8o Assuming the driver mass to be 80 kg and the total mass of the bike to be 20 kg we can calculate the total resistive force Pr = s FN + W sin ? = 0.005 ? 100 ? 9.81 + 100 ? 9.81 ? sin 8o Pr = 141.43 N In order to calculate the torque required by the motor/engine to start we have to assume the diameter of the tyre of the bicycle. The average diameter ranges from 55cm to 70 cm. Taking d =70 cm Tr= Pr ? 0.35 m Tr= 49.5 N m The power rating required will be Power = Tr ? 2?N/60 (N = 50) Power = 260 W The power rating of motors and engines provide a factor of safety of more than 5 as the power required is 260 W. The power rating of the outpouring can be computed by employing the following calculations Average speed of the bike = 15 mph maximal Distance to be travelled = 50 miles Discharging time of the battery = 3.3 hrs Power rating of battery = 45 A ? 3.3 hr = 150 Ahr 7. Produce a detailed PDS based on quantified data The manufactu ring form is based on a detailed PDS (Musharavati). The various relevant elements of PDS for the harvest are mentioned below 1. bleed and Performance The function of the product is to provide an environment friendly means of transport for tourists in a countryside resort. The performance is enhanced by proposing solutions which can provide means of transport with minimum exhaust. 2. Environment The product is environment friendly because there is no exhaust and thus no addition of harmful chemical substance compounds to the environment. The design will be in accordance with the emission standards like euro 3 and USEPA. 3. Ergonomics epoch developing the product ergonomic principles are kept in mind according and the design will be carried out according to the ergonomics principles. The ergonomics are mainly concerned with the position of the seat, institution rest and paddles and the convenience in the operation of control mechanism. The overall weight of the bicycle should not be greater than 30 kg. 4. Safety The safety is very important and the safety and protection guidelines according to the manufacturing standards provided by ASME and ASTM. 5. Materials The selection of materials should be done according to the ease of use and feasibility of manufacturing according to the local conditions. The proposed materials are aluminium and iron. 6. Competition The product under consideration i.e. the environment
