Worked Solution & Example Answer:Calculate the following: 11.1.1 The area of the ram if the diameter of the cylinder is 110 mm - NSC Mechanical Technology Fitting and Machining - Question 11 - 2023 - Paper 1

Step 1

The area of the ram if the diameter of the cylinder is 110 mm.

Answer

To calculate the area of the ram, we use the formula for the area of a circle:

$A = \frac{\pi D^2}{4}$

Substituting the diameter (D = 0.110 m):

$A = \frac{\pi (0.110)^2}{4} = 0.0095 m^2$

Step 2

Force applied on the small piston (plunger).

Answer

Using Pascal's principle, the force on the plunger can be calculated using the formula:

$f = \frac{F A_{plunger}}{A_{ram}}$

where F = 350 N and the area of the plunger is given as $0.005 m^2$ . Hence,

$f = \frac{350 \times 0.005}{0.0095} \approx 184.21 N$

Step 3

The displacement h of the small piston (plunger) in mm.

Answer

The displacement can be calculated using the equation:

$h = \frac{A_{ram} \times H}{A_{plunger}}$

Where H = 25 mm = 0.025 m. Thus,

$h = \frac{0.0095 \times 0.025}{0.005} = 0.0475 m = 47.5 mm$

Answer

Pressure gauges are used to determine the pressure being exerted in the system, which helps to adjust control valves, ensure safety, and indicate if there are any leaks present.

Step 5

State ONE advantage of applying pneumatics in a system.

Answer

One advantage of applying pneumatics is that pneumatic tools are very environmentally friendly and clean in operation.
