Abstract

The Poverty Crusher team built a human-powered rock breaking device for the women in Nepal who make $1.50 - $3 per day crushing rocks. A prototype jaw-type rock crusher was designed and built over a period of several months. However, the device was unable to break rocks due to excessive bending in the connection points of the frame and in the crushing faces. Improvements were suggested for the next prototype, which include increasing the second moment of inertia of the crushing faces, using a welded frame, and generally decreasing the cost and weight of the device.
