ScanSolve AI Tutor · Accepted Answer

Here is the solution for the visible parts of the question: c) Using the graph, find the breaking strength of the manila and poly-propene at the diameter of 15 mm. Step 1: Locate 15 mm on the x-axis (Diameter of rope). Step 2: Trace vertically up from 15 mm to intersect both the manilla rope curve and the poly-propene rope curve. Step 3: Trace horizontally from these intersection points to the y-axis (Breaking strength) to read the values. For Manilla rope: At 15 mm diameter, the breaking strength is approximately 200 N. For Poly-propene rope: At 15 mm diameter, the breaking strength is approximately 400 N. d) State any two disadvantages of the material from which poly-propene is made to the environment. Poly-propene is non-biodegradable, meaning it does not break down naturally in the environment and can persist for hundreds of years, contributing to plastic pollution. Its production relies on fossil fuels, which are non-renewable resources, and the manufacturing process can release greenhouse gases, contributing to climate change.
