A gymnast does a one-arm handstand. The humerus, which is the
upper arm bone between the elbow and the shoulder joint, may be
approximated as a 0.29-m-long cylinder with an outer radius of 1.20
x 10-2 m and a hollow inner core with a radius of 4.2 x
10-3 m. Excluding the arm, the mass of the gymnast is 68
kg. Bone has a compressional Young's modulus of 9.4 x
109 N/m2. (a) What is the
compressional strain of the...

The humerus, which is the upper arm bone between the elbow and the shoulder joint, can be approximated as a 33 -cm-long hollow cylinder with outer radius 1.05 cm and inner radius 0.43 cm. Suppose a gymnast whose arm bone has these dimensions does a one-arm handstand. Excluding the arm, the mass of the gymnast is 65 kg. a) What is the compressional strain of the humerus? Use the value 1.4×1010 N/m2 for Young's modulus. b) By how much is...

The humerus, which is the upper arm bone between the elbow and the shoulder joint, can be approximated as a 33 -cm-long hollow cylinder with outer radius 1.05 cm and inner radius 0.43 cm. Suppose a gymnast whose arm bone has these dimensions does a one-arm handstand. Excluding the arm, the mass of the gymnast is 66 kg. (calculators allowed) (a) What is the compressional strain of the humerus? Use the value 1.4×1010 N/m2 for Young's modulus. (b) By how...

The drawing shows three identical springs hanging from the ceiling. Nothing is attached to the first spring, whereas a W = 5.05-N block hangs from the second spring. A block of unknown weight hangs from the third spring. From the drawing, determine the spring constant (in N/m) and the weight of the block hanging from the third spring. (a) the spring constant N/m (b) the weight of the block hanging from the third spring N

A U-tube contains liquid of unknown density. An oil of density
770 kg/m³ is poured into one arm of the tube until the oil column
is 13.5 cm high. The oil-air interface is then 4.5 cm above the
liquid level in the other arm of the U-tube. Find the density of
the liquid.
