Many caterpillars construct cocoons from silk, one of the strongest naturally occurring materials known. Each thread is typic- 2.0 um in diameter, and the silk has a Young's modulus of 4.0 x 10° N/m2. Assuming that there is no appreciable space between the parallel strands, how many strands N would be needed to N = stra make a rope 8.2 m long that would stretch only 1.02 cm when supporting a pair of 83-kg mountain climbers? Again assuming that there is no appreciable space between the parallel strands, what would be the diameter d of the rope? d =

A surgeon is using material from a donated heart to repair a patient's damaged aorta and needs to know the elastic characteristics of this aortal material. Tests performed on a 16.0 em strip of the donated aorta reveal that it stretches 3.75 cm when a 1.50 N pull is exerted on it. (a) What is the force constant of this strip of aortal material? (b) If the maximum distance it will be able to stretch when it replaces the aorta in the damaged heart is 1.14 cm, what is the greatest force it will be able to exert there?
Many caterpillars construct cocoons from silk, one of the strongest naturally occurring materials known. Each thread is typically 2.0 µm in diameter, and the silk has a Young's modulus of 4.0 x 10° N/m2. Assuming that there is no appreciable space between the parallel strands, how many strands N would be needed to N = strands make a rope 8.6 m long that would stretch only 1.02 cm when supporting a pair of 85-kg mountain climbers? Again assuming that there is no appreciable space between the parallel strands, what would be the diameter d of the rope? d = cm
Find the minimum diameter of a (50 m)-long nylon string that will stretch no more than (1 cm) when a load of (70 kg) is suspended from its lower end. Assume that the Young modulus equals to 3.51*10 N/m? 3.35 cm 3.53 cm 35.3 cm 33.5 cm
During a tensile strength experiment, a small diameter fibre is elongated by a force of 0.0250 N. The fibre has an initial length of 0.200 m and stretches 4 x 102 m. Determine the diameter of the fibre? The Young's modulus for the material being tested is 7.60 x 1010 Pa.
A man with a mass of 68.3 kg stands on one foot. His femur has a cross-sectional area of 8.00 cm2 and an uncompressed length 50.4 cm. Young’s modulus for compression of the human femur is 9.40 × 109 N/m2. What is the fractional length change of the femur when the person moves from standing on two feet to standing on one foot?
A spring of unstreched length 25 cm is pulled in a horizontal direction with 150 N force. Since we apply a force in a horizontal direction, the spring is stretched to 28 cm. Now we suspend the spring from a hook in a vertical direction and attached a 15 kg mass at the bottom. How long my spring will stretch?
