3) A torsion spring is used in a hand-held spring clamp. The jaws of the clamp are 1.5 inches from the pivot. The spring angle is 45° when the clamp is closed and 0° when the clamp is open. Determine torsional spring constant, clamping force when closed and clamping force when open. Use units of torque/rev for torsional spring constant. Include leg length in Na calculations.

A spring with a 4-kg mass and a damping constant 3 can be held stretched 1 meters beyond its natural length by a force of 4 newtons. Suppose the spring is stretched 2 meters beyond its natural length and then released with zero velocity, In the notation of the text, what is the value ?2−4??c2−4mk? m2kg2/sec2m2kg2/sec2 Find the position of the mass, in meters, after t seconds. Your answer should be a function of the variable t with the general form...

Design a straight ended helical torsion spring for a static load 200 N-m at a deflection of 45 deg with a safety factor of 1.8. Specify all parameters necessart to manufacture the spring state all assumntions. You make the following design choices: *Use unpeened oil tempered wire with 40mm long, straight ends. The coil is loaded to close it * Design safety factory Nyd=1.8 *spring index C=11 *Yield Strength Factor K=0.85 *length of the ends L1=40 mm=L2 *Material choice =...

A lunch tray is being held in one hand, as the drawing illustrates. The mass of the tray itself is 0.200 kg, and its center of gravity is located at its geometrical center. On the tray is a 1.00 kg plate of food and a 0.150 kg cup of coffee. Obtain the force T exerted by the thumb and the force F exerted by the four fingers. Both forces act perpendicular to the tray, which is being held parallel to...

Two different machines, A and B, used for torsion tests of steel wire were tested on 12 pairs of different types of wire, with one member of each pair tested on each machine. The results (break angle measurements) were as follows: Machine A: 32, 35, 38, 28, 40, 42, 36, 29, 33, 37, 22, 42 Machine B: 30, 34, 39, 26, 37, 42, 35, 30, 30, 32, 20, 41 [a] Construct a side-by-side boxplot to display the two data sets...

Highlight 3 different resistance training exercises that could be used to overload muscles of the hand and forearm contributing to differing types of grip strength Please justify why such exercises would be beneficial and put them into a practical scenario (training for sport, rehabilitation, bodybuilding, anti-aging..... etc). You may select exercises that primarily target other joints and muscle groups as long as they still provide sufficient enough stimulus to the forearm, wrist, and hand to improve grip strength

Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes them apart and they then fly off in opposite directions, free of the spring. The mass of A is 2.00 times the mass of B, and the energy stored in the spring was 50 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what...

A company claims to have invented a hand-held sensor that can detect the presence of explosives inside a closed container. Law enforcement and security agencies are very interested in purchasing several of the devices if they are shown to perform effectively. An independent laboratory arranged a preliminary test. If the device can detect explosives at a rate greater than chance would predict, a more rigorous test will be performed. They placed four empty boxes in the corners of an otherwise...
