V – Belt is a belt, which is used to create a link between two or more_______. They are also used as a source of motion, efficient power transmission or to track the relative moment.
Correct Answer
A. Rotating Shafts
Explanation
A V-Belt is a type of belt that is used to create a link between two or more rotating shafts. It is used to transmit power efficiently and track the relative motion between the shafts.
2.
MSB is dealing in which company’s V – Belts?
Correct Answer
D. Mitsuboshi
Explanation
MSB is dealing in Mitsuboshi's V-Belts.
3.
What type of V – Belts have the maximum demand?
Correct Answer
C. Classical V belts
Explanation
Classical V belts have the maximum demand because they are the most commonly used type of V belts. They are known for their versatility and are used in a wide range of applications, including industrial machinery, automotive engines, and agricultural equipment. Classical V belts are cost-effective, durable, and provide efficient power transmission. They have a trapezoidal cross-section and are designed to handle high-speed and high-torque applications. Due to their widespread use and reliability, classical V belts have a higher demand compared to other types of V belts.
4.
What are the materials used to construct Mistuboshi V – Belts?
Correct Answer
D. Polyester, Fiber Glass & Aramid Fibers
Explanation
Mitsuboshi V-Belts are constructed using polyester, fiber glass, and aramid fibers. These materials are used to provide strength, durability, and flexibility to the belts. Polyester is known for its high tensile strength and resistance to stretching, while fiber glass adds rigidity and stability. Aramid fibers, such as Kevlar, are used for their excellent resistance to heat and abrasion. The combination of these materials ensures that the Mitsuboshi V-Belts can withstand heavy loads, high temperatures, and harsh operating conditions.
5.
Who are the top two competitors of MSB?
Correct Answer
C. Fenner & Pix
Explanation
The top two competitors of MSB are Fenner and Pix.
6.
Large amount of oil or grease on V – belt will cause _______ .
Correct Answer
A. Slip
Explanation
A large amount of oil or grease on a V-belt can cause it to slip. When the belt slips, it loses traction and is unable to transfer power effectively. This can result in decreased efficiency and performance of the system that the V-belt is a part of.
7.
Which instrument is used to check the wear of a V – Belt?
Correct Answer
D. Plastic Groove Gauge
Explanation
The plastic groove gauge is used to check the wear of a V-Belt. This tool allows for accurate measurement of the depth of the grooves in the belt, which can indicate the amount of wear and help determine if the belt needs to be replaced. The plastic material of the gauge ensures that it does not damage or scratch the belt during the measurement process.
8.
What are the two categories of V – Belt failure?
Correct Answer
B. Premature & Normal
Explanation
The two categories of V-belt failure are premature and normal. Premature failure refers to the belt breaking or wearing out before its expected lifespan, often due to factors such as incorrect installation, excessive tension, or improper maintenance. Normal failure, on the other hand, occurs when the belt reaches the end of its expected lifespan and wears out naturally over time.

Calculate V - Belt length basis following parameters:
Centre Distance = 27, Diameter of Large Sheave = 14, Diameter of small sheave = 8
Correct Answer
B. 88.54
Explanation
The V-belt length can be calculated using the formula: V-belt length = 2 * Centre Distance + (Diameter of Large Sheave - Diameter of small sheave) + (Diameter of Large Sheave - Diameter of small sheave) / 2. Plugging in the given values, we get: V-belt length = 2 * 27 + (14 - 8) + (14 - 8) / 2 = 54 + 6 + 3 = 63. Therefore, the correct answer is 63. However, none of the options provided match this value, so the correct answer is not available.
10.
Mitsuboshi V – Belts are manufactured as per ___________ & ____________ standards.
Correct Answer
A. DIN 2215 & ISO 4184
Explanation
Mitsuboshi V-Belts are manufactured according to the DIN 2215 and ISO 4184 standards. These standards ensure that the belts are produced with the required specifications and quality control measures in place. DIN 2215 specifies the dimensions and technical requirements for V-belts, while ISO 4184 provides guidelines for the construction and testing of V-belts. By adhering to these standards, Mitsuboshi ensures that their belts meet the industry requirements and deliver reliable performance.
