Building a spiral ramp with angle/gradient restrictions ...

Dear support team For a museum project we are designing a spiral ramp that needs to fulfil building laws concerning the slope gradient. Is there an elegant way to display the angle or the gradient from the 3D object or do I have to calculate it manually? Because of the spiral it is not such a easy thing to quickly calculate it manually. Thanks a lot.

MINE DEVELOPMENT – ACCESS TO DEPOSIT

ramps offer early access to shallow deposits, which develops the ore body expediently, but are generally developed at a gradient of approximately 12 per cent. Decline haulages have become an attractive alternative to shaft hoisting, and over recent years the role of decline access has become more widespread throughout South Africa.

Gradient specifications - Questions and Answers in MRI

2021. 1. 24. · Thus a gradient that ramps from 0 to peak amplitude of 30 mT/m in 0.5 msec would have a slew rate of 60 T/m/s. The slew rate influences the minimum attainable TR and TE for conventional MR imaging and influences the echo spacing in fast spin echo and echo planar applications.
