About This Product
The vane shear test gives the undrained shear strength of soft clay in the laboratory. The vane is pushed into the soil sample and turned by the hand wheel at a slow, steady rate until the soil fails. The pointer shows the angle of torque on the dial, and multiplying the dial reading by the spring factor gives the torque. The shear strength is then worked out from the torque and the vane size. Students use it in soil mechanics practicals. Schools, colleges and distributors in Grenada, France, Equatorial Guinea, Belgium and South Sudan can source the Laboratory Vane Shear Apparatus (Hand Operated) from School Lab Equipment India.
Frequently Asked Questions
Q1. How is the vane rotated?
It is rotated by a hand wheel that operates a worm gear arrangement acting on the upper end of a calibrated torsion spring.
Q2. How is the torque calculated?
The pointer indicates the angle of torque on a dial graduated in degrees, and the dial reading multiplied by the spring factor gives the torque.
Q3. Which springs and container are supplied?
A set of four springs of approximately 2, 4, 6 and 8 kg.cm and a container for the soil sample. A sampling tube of 38 mm I.D. and 150 mm length can also be used as the container.
