Objective The objective of this experiment is to study how a hollow shaft would behave compared with a solid shaft, in terms of strength and rigidity. Sample Calculation For Table 2: Comparing strength and torsional stiffness of solid and hollow shafts with the same outer diameter (12mm) For hollow shaft 12/6 mm, Experimental % change in torsional stiffness, = 305.05-343.64343.64 *100% = -11.23% Theoretical % change in torsional

251 Force Activity 1-1: Introduction to Force Procedure: 1. Place one end of a rubber band around the vertical rod on your table. 2. Stretch the rubber band to a length of 10cm beyond its unstretched length, L0. [pic] 3. Place two rubber bands around the rod and stretch them together a length of 10cm Question 1-1: How does the combined force of two rubber bands compare to the force of just one rubber band? 1. Repeat with 3, 4 5 rubber bands. Activity 1-2: Measuring Force with

Exercise 1: Flat bench press (which trains Pectoralis major). As you lower the bar towards the chest is the eccentric phase of the movement, as you raise the bar back up is the concentric phase of the movement. The isometric phase is when no movement occurs. If you perform the bench press exercise in a slow and controlled manner, I would say there are two isometric phases: the first one is when you have lowered the bar to chest and right before you start pushing it up again (at the end of the eccentric

Coordinate systems in geometry are systems which use numbers known as coordinates to determine the positions of points in space (Wolfram). The two coordinate systems we will be using in this problem are the Cartesian coordinate system and the polar coordinate system. The Cartesian coordinate system specifies points in a plane using pairs of numerical coordinates, which in this case are the x and y values of point A, point B, and point C listed in the diagram (Wolfram). For example, point C on the

increase the force of friction via increasing the gravitational forces, and therefore the normal forces, acting on the cart. Increasing velocity has an exponential effect on the carts kinetic energy and by increasing it one would increase the velocity of the cart at every other point on the roller coaster. This has inherent risk, as if the cart is going too fast at the crest of hills or too slow at the top of a loop the cart will derail.

even a ship, the propeller applies to it. So what does the Propeller do? According to Newton’s Third Law of Action and Reaction the propeller takes into account this force by using the turbine or motor applicable in the vehicle. As the motor starts to roll causing a force the propeller uses it to create an equal and opposite force, this provides subsequent power in order for the vehicle to move forward. In basic the propeller consists of 2 parts the blades and the hub or the center. The hub is the
