A flat belt has an effective angle of =. The material of a V-belt or multi-V serpentine belt tends to wedge into the mating groove in a pulley as the load increases, improving torque transmission. [6] For the same power transmission, a V-belt requires less tension than a flat belt, increasing bearing life. [5]
The most common type of CVT uses a V-belt which runs between two variable-diameter pulleys. [1] The pulleys consist of two cone-shaped halves that move together and apart. The V-belt runs between these two halves, so the effective diameter of the pulley is dependent on the distance between the two halves of the pulley.
It is a stepless, fully-automatic transmission, consisting of a V-shaped drive-belt, and two pulleys, each of two cones, whose effective diameter can be changed so that the "V" belt runs nearer the spindle or nearer the rim, depending on the separation of the cones. These are synchronized so that the belt always remains at the same optimal tension.
A tension meter is a device used to measure tension in wires, cables, textiles, Mechanical belts and more. Meters commonly use a 3 roller system where the material travels through the rollers causing deflection in the center roller that is connected to an analog indicator or load cell on digital models.

Following the international credit crisis and spikes in crude oil prices, Pakistan's economy could not withstand the pressure, and on 11 October 2008, the State Bank of Pakistan reported that the country's foreign exchange reserves had gone down by $571.9 million to $7,749.7 million. [65]
The tension defused in a short time and Pakistan moved its troops away from the border. 2016–2018 India–Pakistan border skirmishes : On 29 September 2016, border skirmishes between India and Pakistan began following reported " surgical strikes " by India against militant launch pads across the Line of Control in Pakistani-administered ...
Pakistan, [e] officially the Islamic Republic of Pakistan, [f] is a country in South Asia. It is the fifth-most populous country, with a population of over 241.5 million, [g] having the second-largest Muslim population as of 2023. Islamabad is the nation's capital, while Karachi is its largest city and financial centre.
