Exercises (2.1) A compression sup ompression support is constructed by welding two round solid steel bars end-to-end as shown use for the Young\'s modulus are 17 GPa and for the compressive strength 190 MPa. below. I the allowable stress in compression is 100 (2.5) Consider the Campanile (shown in the photo- MPa, what is the allowable load P1, if P2 = 150 kN grap. Introduce appropriate variables for the relevant dimensions, densities, etc., and derive an expression for he internal force field, R(r). You may ignore the complexities associated with the openings for the bells, but make sure you account for the taper at the top. diameter 100 mm diameter 50 mm (2.2) Consider one of the concrete specims shown in Fig. 2.8. In an experiment with applied end-forces a stress of 4.0 ksi was required to axially crush the cylinder. How much force did the testing machine exert on the specimen at crush? (2.3) A 10-m long steel linkage is to be designed so that it can transmit 2 kN of force without stretch- ing more than 5 mm nor having a stress state greater than 200 N/mm2 If the inkage is to be constructed from solid round stock, what is the minimum required diameter? (2.4) Estimate the amount of force would take to (axially) crush your femur. Reasonable values to

Solution

Size of femur bone is approximately 48 centimeters (18.9 in) in length and 2.34 cm (0.92 in) in diameter .So consider bone to be cylinder of above dimensions .

Compressive force=compressive strength*cross secrion area of bone

crushing force =190*10⁶ *(pi/4)*(2.34/100)² Newton

.Answer is 81668.574 Newton(approx)
