Zero camber is straight down through the tire to the ground. Engineers use an angle finder and a straight edge to determine and adjust that angle.Ĭaster measures the angles formed between the upper and lower ball joints. Zero camber creates a 90-degree angle between the roadway and the center line of the tire. Toe-in/Toe-out gauges have a bar long enough to measure between the center of the left and right tires, with a prong at each end of the bar that slips into the tread groove on each tire without penetrating or piercing it.Ĭamber measures the inward or outward angle of the tire and the pavement. All three of these tools ensure that vehicle performance stays "on spec" or within the recommended manufacturer's specifications. The tips of each leg curve outward for measuring inside diameters.Ĭaster/Camber/Toe-in testers measure tire angles and help engineers align the steering on vehicles. You use inward-curving calipers to measure outside diameters. Calipers have two legs instead of just the one, and they are curved.

This multitool allows the mechanical engineer to reattach broken, corroded or loose wires, to restore functionality.Ĭalipers look a lot like a draftsman's compass: that tool you slide a pencil into to draw circles in math class. This tool might also include a sharp tool for piercing sheet metal, a pair of mini scissors, and several flat-head or Phillips head drivers.

Mechanical engineers often have to cut and strip wires, so most carry at least one multi-tool with pliers. Ratcheting screwdriver sets also include Posidriv screw bits, used to avoid "cam-out" or slippage from the slot of Phillip's head screws, and the bow-tie-shaped clutch screw, which was initially used in automobiles between 19, as well as in travel trailers, as late as the 1970s. You sometimes see the two-pronged spanner bit in your ratcheting screwdriver set, used to prevent tampering with bathroom stall doors. Tri-wing screw slots look a little like the three central rays of a car's steering wheel.

Some older video game systems used tamper-proof drivers such as the Tri-wing. It includes the familiar flat-head and Phillips bits, but it also provides more specialized drivers and bits, such as the hexagonal Allen bit and the six-lobed Star, along with the square-slotted Robertson bit. A ratcheting screwdriver set contains a screwdriver handle and multiple bits.
