Which of the following is not a type of cylinder arrangement in IC Engines.
Zig-zag engines
IC Engine Cylinder Arrangements Explained
Internal Combustion (IC) engines come in various configurations, defined by how the cylinders are arranged relative to the crankshaft. Understanding these arrangements is key to knowing engine design and characteristics.
Common Cylinder Configurations in IC Engines
Let's look at the typical cylinder arrangements mentioned:
- V-engines: Cylinders are arranged in two banks, angled to form a 'V' shape above the crankshaft. Examples include V6, V8, and V12 engines, commonly found in cars and motorcycles.
- Radial engines: Cylinders are arranged in a circular pattern around a single crankshaft. This design was historically popular in aircraft due to its cooling efficiency and compact size for the number of cylinders.
- X-engines: This is a less common arrangement where four banks of cylinders are arranged in an 'X' configuration around the crankshaft. Each bank might be angled, creating a complex but powerful engine design, like the Rolls-Royce Vulture.
Identifying Non-Standard Cylinder Configurations
The question asks which option is NOT a recognized type of cylinder arrangement in IC engines.
- Based on established engine terminology, V-engines, Radial engines, and X-engines (though less common) are all known configurations.
- Zig-zag engines do not correspond to any standard or recognized classification of cylinder arrangements in internal combustion engines. This term likely describes a non-standard or hypothetical layout rather than an actual engine type.
Therefore, the correct answer is the one that doesn't represent a known IC engine configuration.

A stone is thrown horizontally from the top of a 20 m high building with a speed of 12 m/s. It hits the ground at a distance R from the building. Taking g = 10 m/s2 and neglecting air resistance will give :
A sphere of volume V is made of a material with lower density than water. While on Earth, it floats on water with its volume f1V (f1 < 1) submerged. On the other hand, on a spaceship accelerating with acceleration a < g (g is the acceleration due to gravity on Earth) in outer space, its submerged volume in water is f2V. Then:
A railway wagon (open at the top) of mass M1 is moving with speed v1 along a straight track. As a result of rain, after some time it gets partially filled with water so that the mass of the wagon becomes M2 and speed becomes v2. Taking the rain to be falling vertically and the water stationery inside the wagon, the relation between the two speeds v1 and v2 is :
Consider the following statements:
1. Distance between the longitudes becomes zero on North Pole and South Pole.
2. Distance between the longitudes is maximum on the Equator.
3. Number of longitudes is more than number of latitudes.
Which of the statements given above is/are correct?
One block of 2⋅0 kg mass is placed on top of another block of 3⋅0 kg mass. The coefficient of static friction between the two blocks is 0⋅2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking acceleration due to gravity as 10 m/s2, the maximum value of the frictional force is :
