Arig must hoist a load of 2 lbf. the drawworks can provide a maximum input power of 800 hp. ten lines are strung between the crown block and the travelling block and the deadline is anchored to a derrick leg on one side of the v-door m) calculate the static tension in the fast line when upward motion is impending. n) calculate the maximum hook horsepower available. o) calculate the maximum hoisting speed. p) calculate the derrick load when upward motion is impending. q) calculate the maximum equivalent derrick load. r) calculate the derrick efficiency factor.

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
