The 100-lb platform rolls without slipping along the 10 degree incline on two pairs of 16-in. diameter wheels. each pair of wheels with attached axle weighs 25 lb and has a centroid radius of gyration of 5.5 in. the platform has an initial speed of 3 ft/ sec down the incline when a tension t is applied through a cables attached to the platform. if the platform acquires a speed of 3ft/sec up the incline after the tension has been applied for 8 seconds, what is the average value of the tension in the cable?

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.
