Question
Required information
Water in a channel is retained by a gate with 10 cm width (into the plane of the figure). The gate is supported by a pin at B
and by frictionless contact with the bottom of the channel at A. The gate is outfitted with a prewound torsional spring at B
with stiffness k+= 75 N-m/rad.

ces
The vertical wall BC is fixed in position. If the gate has negligible weight, determine the amount o the spring must be prewound so
that the gate will begin to open when d= 60 cm. (Round the final answer to four decimal places.)
The amount o the spring must be prewound is
