Technician a says that the engine block is the solid frame from which all automotive and truck engines are constructed and is made out of cast iron or aluminum. technician b says that the cylinders are deep, can-shaped holes that are drilled into the engine block, and that the up-and-down movement of the pistons inside the cylinders produces the power needed to operate the vehicle. who is right? a. neither technician a nor b b. both technicians a and b c. technician a only d. technician b only

Both technicians are correct.

Also known as a cylinder block, an engine block is the solid frame that supports all the major components of an engine. It is in an engine block where the crankshaft spins and the pistons move up and down in the cylinder bores. The material selected for engine block is either the aluminum alloy or the gray cast iron for good thermal conductivity and fluidity. The cylinder heads secured firmly to the top of the engine block facilitates the upward and downward movements of the piston and turn the crankshaft. This ultimately moves the wheels. They are arranged in a single line or similar linear fashion and convert it reciprocating motion to your wheels.
