Point "P", as shown below, is located between nodes 2 and 3 of a quadratic 1D bar element. Workout the location of point "P" in physical coordinate system (x coordinate) if the location of point "P" in the natural coordinate is p=0.05. Suppose that the locations of node 1 and node 3 are x1 11.2 mm and x3=38.0 mm. respectively. (Hint: the answer should be in mm and you need to round your answer after 4 decimal points) 1 X1 2 x2 * P 3 X3
For all three objects represented in axonometric view, you have to create: - three orthogonal views ( front, top and side) - put all necessary dimension lines on all the orthogonal views - create an oblique axonometric view
Dynamics of Rigid Bodies 1.) From the top of a tower an object is thrown vertically downward with a velocity of 20 m/s. What is the velocity of the object after it has fallen 60 metres? 2.) A diver jumps from a height of 3.0 metres above the height of the water and touches the surface 1.0 s later. What was his velocity when he hit the water? 3.) A motorcyclist, travelling at a speed of 30 m/s, sees an obstacle 100 metres in front of him and puts on the brakes. He hits it 5.0 seconds later. If the motorcycle slows down uniformly, how fast was it going at the instant of the collision?

In a nutshell, a smaller rock is propelled into the air as a huge counterweight in the back falls down, effectively converting gravitational potential energy into kinetic energy for the rock and the weight. But, since the rock is smaller.. it is propelled at a much faster velocity! Let's say we wanted to hurl a 50 kg boulder at a castle wall 100 meters away. Our wooden structure for the trebuchet is 10 meters tall, so that is the maximum distance the counterweight can fall. Assuming the launch angle is a perfect 45 degrees, and the boulder is released from ground level, derive the needed mass of the counterweight that will give the boulder enough kinetic energy to reach the base of the castle walls. You may assume no energy is "lost" due to friction, and ALL the counterweight's gravitational potential energy is converted into the boulder's kinetic enerqy. (HINT: You will need to employ 2D kinematics to find the needed final velocity, then use that final velocity in an energy equation…
Drop-load (I)This exercise is part of a series of problems aimed at modeling a situation by progressively refining our model to take into account more and more parameters. This progressive approach is very close to what professional scientists do! context We want to lower a suspended load in a controlled way, so that it hits the ground with a speed whose modulus is not too great. To do this, the suspended load (B) is connected by a rope passing through a pulley to another mass (A), which can move on a horizontal surface. To slow down the descent, we added a spring behind the mass (A). Information The masses of the charges A and B are known.The mass of the rope itself is negligible (very small compared to the loads).The pulley has negligible mass and can rotate without friction.The charge ? is initially stationary and is at a known height h.The surface on which mass A is placed is horizontal.There is no friction between mass A and the surface on which it is placed.The string attached…
FLUID STATICS. Only round off in the final answer. Use 3 decimal places. Thank you!Allison places her coffee mug on a spinner and rotates it around its axis. At rest, the mug is 10 cm deep and 6 cm in diameter, and it holds coffee 7 cm deep. What is the maximum angular rotation she can do in rad/s without spilling her coffee?
You are learning to play the violin. One end of the string is vibrating from the bow running along one end. The other end is tied down. The length of the string we will be looking at is 30 cm and the total mass of the string is 0,32 g. We will be modeling this as a standing wave on a string. You being to play the violin and play a note which has a frequency of 440 Hz. You (having incredible eyesight) see that there are 3 anti-nodes on the string forming a perfect sinusoidal wave (shown in diagram). L i) What is the wavelength of this standing wave? ii) What is the speed of the traveling waves that make up this standing wave? iii) What is the tension of the string? iv) Suppose you increase the tension of the string until you get a new standing wave. Will this standing wave have two antinodes or four antinodes? Explain. (You are still at a frequency of 440 Hz)
Suppose you're converting a bill of materials for machining feedstock from the British gravitational (U.S. system) of units to International System (SI) units. Your goal is to have all of the material quantities in kilograms. Your bill of materials lists values for required weights of brass rod in pounds. To convert to these values to kilograms you first you divide by gravitational acceleration in feet per second squared to get a mass in slugs, then convert slugs to kilograms using standard conversion factors.
