Final answer:
The angled design of some rods in engineering allows for a larger rod bearing, makes removal and installation easier, but does not affect the compression ratio.
Step-by-step explanation:
The purpose of the angled design of some rods in engineering is to use a larger rod bearing and still get the rod through the liner. By angling the rod, the distance between the crankshaft and the cylinder wall can be reduced, allowing for a larger diameter rod bearing to be used while still fitting within the available space. This increases the strength and durability of the rod.
Additionally, the angled design of the rod facilitates easy removal and installation. It provides better access and clearance when working on the engine, making it more convenient to detach and reattach the rod.
However, the angled design of the rod does not directly make the compression ratio adjustable. The compression ratio is primarily determined by the geometry of the piston and cylinder, not the design of the connecting rod.
