489CH4021Certificate in Foundation Studies L2 (with specialisation option)2.0220.00.0Demonstrate knowledge of simple machines. 1.1 Simple machines are
identified and described according to mechanical engineering
practice. Range: simple machines - first, second, and third order
levers; wedge, screw; pulley; wheel and axle. 1.2 Calculations
involving length, forces, moments, torque, work, and power are
carried out for simple machines. Range: simple machines - lever;
wedge, screw; pulley; wheel and axle. Evidence of calculations for
three simple machines is required. 1.3 Calculations involving
symmetrical triangular forces are performed.
Demonstrate knowledge of friction. 2.1 The nature of friction is
explained with reference to applied forces and the coefficient of
friction. 2.2 Static, sliding, and rolling friction are
distinguished. 2.3 Advantages and disadvantages of friction are
outlined. 2.4 Methods to reduce friction are outlined.
Demonstrate knowledge of Pascal's Law. 3.1 Pascal?s Law is stated
and its significance in mechanical engineering explained. 3.2
Calculations involving hydrostatic pressure and piston forces in
compressed fluid situations are performed..
