Question 1 of 27070

During the power stroke, the side thrust of a trunk type piston is a result of the angle __________.

🔍 Key Concepts

• Trunk-type piston design and how it transfers forces to the cylinder wall • The geometry between crank, connecting rod, and piston during the power stroke • How side thrust is created when a straight-line motion is driven by a rotating crank

💭 Think About

• Visualize the piston at mid-stroke during the power stroke: which parts are not in a straight line, and where does the angularity occur? • Ask yourself: which angle causes the piston to push sideways against the cylinder wall instead of only straight down? • Consider which components actually touch or guide the piston sideways in the cylinder, and which ones only rotate about a shaft.

✅ Before You Answer

• Identify which members are directly connected to the piston and control its motion in the cylinder bore • Determine where the angularity shows up when the crankshaft has rotated away from top dead center • Eliminate any option that describes an angle between parts that do not directly cause lateral force on the piston skirt or cylinder wall
