ROTATING PILLARS OF INDIAN TEMPLE

Rotating Machines Of Ancient India: Indians Were Using Advanced technology To Build These Marvels

In modern days, to rotate two objects that correspond to each other,  we use ball bearings. ​​A ball bearing is a type of rolling element that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (for example a hub or shaft). As one of the bearing races rotates, it causes the balls to rotate as well.

Uncovering the Mysteries of Modhera Sun Temple: A Masterpiece of Ancient Indian Maru-Gurjara Architecture

The Sun Temple of Modhera was constructed during the reign of Bhima I of the Chaulukya dynasty. In 1024-1025, Bhima’s kingdom was invaded by Mahmud of Ghazni, and a group of around 20,000 soldiers attempted to stop his advance at Modhera, but were unsuccessful. The shrine proper of the Sun Temple was built after this invasion. An inscription “Vikram Samvat 1083” is found on a block in the western wall of the cella, which corresponds to 1026-1027 CE. The inscription is upside down, which suggests that the cella was destroyed and reconstructed. However, due to the position of the inscription, it is not considered as the date of construction. On stylistic grounds, it is known that the Kunda with its corner shrines was built earlier at the beginning of the 11th century.
