I'M STUCK! A cable used to lift heavy materials like steel I-beams must be strong enough to resist breaking even under a load of 1.3  106 N. For safety, the cable must support twice that load. (a) What cross-sectional area should the cable have if it's to be made of steel? m2(b) By how much will a 9.0-m length of this cable stretch when subject to the 1.3  106-N load? m

By how much does a 65.0kg mountain climber stretch her 0.800cm diameter nylon rope when she hangs 35.0m below a rock outcropping? (For nylon, Y=1.35109Pa. )

What Is Static Equilibrium? Problems 13 are grouped. 1. C A ball is attached to a strong, lightweight rod (Fig. P14.1). The rod is supported by a horizontal pin near the top. The ball is at rest. Is the ball in static equilibrium? If not, why not? If so, which type of equilibrium is itstable, unstable, or neutral? Hint: What would happen if you displaced the ball slightly? FIGURE P14.1

Alarge uniform cylindrical steel rod of density =7.8g/cm3 is 2.0 m long and has a diameter of 5.0 cm. the rod is fastened to a concrete floor with its long axis vertical.what is the normal stress in the rod at the cross-section located at (a)1.0 mfrom its lower end?(b)1.5 m from the lower end?

Two thin rods, one made of steel and the other of aluminium, are joined end to end. Each rod is 2.0m long and has cross-sectional area 9.1mm2 . If a 10,000N tensile force is applied at each end of the combination, find: (a) stress in each rod; (b) strain in each rod; and, (c) elongation of each rod.

A steel cable 2.00 m in length and with cross-sectional radius 0.350 mm is used to suspend from the ceiling a 10.0-kg model aircraft that is flying in a horizontal circle with an angular speed of 6.00 rad/s. What is the strain produced in the cable?

A copper wire is 1.0 m long and it diameter is 1.0 mm. if the wire hangs vertically how much weight must be added to its free end in order to stretch it 3.0mm?

A cable used to lift heavy materials like steel I-beams must be strong enough to resist breaking even under a load of 1.7  106 N. For safety, the cable must support twice that load. (a) What cross-sectional area should the cable have if it's to be made of steel?   (b) By how much will a 7.0-m length of this cable stretch when subject to the 1.7  106-N load?

A cable used to lift heavy materials like steel I-beams must be strong enough to resist breaking even under a load of 2.0 x 106 N. For safety, the cable must support twice that load. (a) What cross-sectional area should the cable have if it's to be made of steel?_____m2(b) By how much will a 8.0-m length of this cable stretch when subject to the 2.0 x 106-N load?____m

How much will a steel wire 2 m long and 1 mm diameter stretch under a 5 kg. wt. load? (Y=2 x 10" N/m, g=9.8 m/s²).
