Engineering Drawing

Technical drawing has been around since ancient times. As in the ancient Renaissance, complicated drawings were created, including Leonardo da Vinci's drawing. Modern engineering drawing, including its specific orthographic projection with scale conventions, began in Europe (France) during the early stages of Industrialization. L.T. C. Rolt also made some of Marc's drawings for its block-making machinery (in 1799) that also may have contributed significantly to British engineering technology. Since he learned the art of presenting three-dimensional(3D) items in a two-dimensional(2D) plane, as we now term mechanical drawing.

Q2/ A dry single plate clutch is to be designed for an automotive vehicle whose engine is rated to give 100 kW at 2400 r.p.m. and maximum torque 500 N-m. The outer radius of the friction plate is 25% more than the inner radius. The intensity of pressure between the plate is not to exceed 0.07 N/mm?. The coefficient of friction may be assumed equal to 0.3. The helical springs required by this clutch to provide axial force necessary to engage the clutch are eight. If each spring has stiffness equal to 40 N/mm, determine the dimensions of the friction plate and initial compression in the springs
2 (b) A multi-plate clutch has four pairs of frictional surfaces, each of internal diameter 120 mm and external diameter 200 mm. If the coefficient of friction is 0.3 and the uniform pressure condition can be assumed, what is the required spring force when the plates transmit 20 kW at 1400 rpm?
A multi-plate clutch must transmit 11 kW of power without slipping at 1500 rev/min. The coefficient of friction is 0.3. The inner and outer radis are 30 and 85 mm respectively. The axial force applied to the plates is 780 N. Determine the number of plates required using.
An automotive-type clutch, as shown in Figure 18.2, has inside and outside diameters of 160 and 240 mm, respectively. Clamping force is provided by nine springs,each compressed 5 mm to give a force of 900 N when the clutch is new. The moldedfriction material provides a conservatively estimated coefficient of friction of 0.40when in contact with the flywheel and pressure plate. Maximum engine torque is280 N # m.(a) What is the safety factor with respect to slippage of a brand new clutch?(b) What is the safety factor after “initial wear” has occurred?(c) How much wear of the friction material can take place before the clutch will slip (assuming no change in coefficient of friction)?

The pressure between the flywheel face and the pressure plate is 159 kN/m² and the coefficient of friction is limited to 0.28. Determine: The torque that can be transmitted by the clutch, The power transmitted at a speed of 350 rpm.
