What is the torque (in ft.lbs.) needed to fracture a bone if:
A typical human tibia is 1.5 cm inside diameter and 5 cm. outside diameter. The polar moment of inertia of this typical tibia is 60.8 cm4. Human bone has a shear modulus of G=3.5. The length of a female adolescent tibia at age 14 is 373 mm or 37.3 cm.
A given spring is stretched by 2mm using an applied force of 30 N. Calculate the stiffness of the spring.
Design a Lever Arm capable of lifting a 0.5kg object such as stone. The force for lifting should be provided by placing coins on the other end of the lever. How many coins would you need? What happen if you shorten or lengthen the lever arm? What does this say about torque?
Weight of coins= 7.4 grams or 0.0074kg

- The tensile modulus of a 0°, 90°, and 45° graphite/epoxy ply is measured as follows to give E₁ = 26.25 Msi, E2 = 1.494 Msi, Ex = 2.427 Msi for the 45° ply, respectively. 1. What is the value Ex for a 30° ply? 2. Can you calculate the values of v12 and G12 from the previously measured three values of elastic moduli?arrow_forwardWhen lifting weights, it turns out the amount of force you need to lift them doesn't necessarily match the dumbbell's weight — in other words, if an object weighs 100 N, the amount of force you actually need to apply is probably not 100 N. Observe the diagram below: You can think of the bones in your arms as rods that rotate about an axis of rotation (your elbow) depending on the magnitude, direction and position of the forces being applied. So in order for your arm to lift the weight, the torque exerted by the bicep should be greater than or equal to the torques being applied by the bones' center of mass and the weight your hand is holding. Notice how the bicep is connected to the arm bone (the radius) at a certain distance from the joint, and applies an upwards tension force (as the bicep contracts in order to lift objects). Show how the magnitude of the tension force exerted by the biceps muscle can differ greatly from the magnitude of the weight.arrow_forwardSteel springs must have a modulus of resilience of at least 2.0 MPa.
