Rear overhang may present a problem in large vehicles such as buses. Long rear overhang would require the driver to pay attention to nearby vehicles when turning at 90 degrees. Since the rear overhang is outside the wheelbase, it may hit a vehicle in the adjacent lane, especially when turning 90 degrees right (in a right-hand drive country).
Eaves must be designed for local wind speeds as the overhang can significantly increase the wind loading on the roof. [7] The line on the ground under the outer edge of the eaves is the eavesdrip, or dripline, and in typical building planning regulations defines the extent of the building and cannot oversail the property boundary.
The standard rail weight for British railways is now 113 lb/yd (56.1 kg/m). Before the 1990s, most diesel locomotives were built to a maximum axle load of 19 long tons (19.3 tonnes; 21.3 short tons) so the maximum locomotive weight was 76 long tons (77.2 tonnes; 85.1 short tons) for a four-axle locomotive and 114 long tons (115.8 tonnes; 127.7 short tons) for a six-axle one.
Typically, it is written in the form x/y, where x is the percentage of weight in the front, and y is the percentage in the back. In a vehicle which relies on gravity in some way, weight distribution directly affects a variety of vehicle characteristics, including handling , acceleration , traction , and component life.
Vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics.
Overhang on 16th century Tomb of Salim Chishti, Fatehpur Sikri, India In architecture , an overhang is a protruding structure that may provide protection for lower levels. Overhangs on two sides of Pennsylvania Dutch barns protect doors, windows, and other lower-level structures.
The farther back the engine, the greater the bias. Typical weight bias for an FF (front engine, front-wheel-drive) is 65/35 front/rear; for FR, 55/45; for MR, 45/55; for RR, 35/65. A static rear weight requires less forward brake bias, as load is more evenly distributed among all four wheels under braking. Similarly, a rear weight bias means ...
A piece added at the foot to create an overhang or change the roof pitch is called a sprocket, or coyau in French. The projecting piece on the gable of a building forming an overhang is called a lookout. A rafter can be reinforced with a strut, principal purlin, collar beam, or, rarely, an auxiliary rafter (see below). Rafter types include:
