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.

Figure Q4: The pendulum

(b) A pendulum consists of a rod AB and disk Cas shown in Figure Q4. The pendulum
is connected with the torsional spring at point A. When 0 = 0°, the pendulum is at
rest, and the torsional spring is untwisted. Rod AB has a mass of mrod = 6 kg, and
disk Chas a mass of maak =2 kg. The pendulum is then released and falls downward
at the instant 0= 90°.
) Determine the mass moment inertia of the pendulum.
(ii) Draw the Free Body Diagram when the pendulum at e = 0° and 0 = 90°.
(iii) Will the angular velocity, o for the pendulum increased when it released and
fell downward from the angle 0° to 90°, if the mass of disk maat, has the
ranged of 2 kg to 6 kg? Proof the calculation. State the answer up to four (4)
decimal places.
