Abstract: A method for managing a virtual classroom is implemented using a system that includes a server, a lecturer device that is associated with a lecturer, and at least one student device that is associated with a student. The method includes: recording, by the lecturer device, a first audio/video (A/V) data stream associated with the lecturer; in response to receipt of the first A/V data stream from the lecturer device, transmitting, by the server, the first A/V data stream to the student device to be presented to the student; recording, by the student device, a second A/V data stream associated with the student; in response to receipt of the second A/V data stream, performing, by the server, a calculation of an attentiveness score associated with attention of the student responding to the first A/V data stream; and transmitting the attentiveness score to the lecturer device.

Abstract: A composite oil pan for a work vehicle engine and a method of forming the composite engine oil pan include forming a sheet of metal into a first pan and open molding a fiber-reinforced polymer resin onto the first pan forming a second pan. The first pan has a first bottom wall and first peripheral walls extending from edges of the first bottom wall to define a sump, the first peripheral walls terminating in a first peripheral flange. The second pan has a second bottom wall and second peripheral walls abutting the first bottom wall and the first peripheral walls, the second peripheral walls terminating in a second peripheral flange. The first pan defines a thin metal structure with an inner surface extending across the first bottom wall, first peripheral walls and first peripheral flange; the second pan reinforces the first pan without abutting the inner surface.
