- A magnesium-alloy wire of diameter d = 4mm and length L rotates inside a flexible tube in order to open or close a switch from a remote location (see figure). A torque Tis applied manually (either clockwise or counterclockwise) at end 5, thus twisting the wire inside the tube. At the other end A, the rotation of the wire operates a handle that opens or closes the switch. A torque T0 = 0.2 N · m is required to operate the switch. The torsional stiffness of the tube, combined with friction between the tube and the wire, induces a distributed torque of constant intensity t = 0.04N m/m (torque per unit distance) acting along the entire length of the wire. (a) If the allowable shear stress in the wire is T allow = 30 MPa, what is the longest permissible length Lmaxof the wire?A bicycle chain consists of a series of small links, where each are 12 mm long between the centers of the pins (see figure). You might wish to examine a bicycle chain and observe its construction. Note particularly the pins, which have a diameter of 2.5 mm. To solve this problem, make two measurements on a bicycle (see figure): (1) the length L of the crank arm from main axle to pedal axle and (2) the radius R of the sprocket (the toothed wheel, sometimes called the chainring). (a) Using your measured dimensions, calculate the tensile force T in the chain due to a force F = 800 N applied to one of the pedals. (b) Calculate the average shear stress T averin the pins.A motor driving a solid circular steel shaft with diameter d = 1.5 in, transmits 50 hp to a gear at B, The allowable shear stress in the steel is 6000 psi. Calculate the required speed of rotation (number of revolutions per minute) so that the shear stress in the shaft does not exceed the allowable limit.
- A steel punch consists of two shafts: upper shaft and lower shaft. Assume that the upper shaft has a diameter d1= 24 mm and the bottom shaft has a diameter d2= 16 mm. The punch is used to insert a hole in a 4 mm plate, as shown in the figure. If a force P - 70 kN is required to create the hole, what is the average shear stress in the plate and the average compressive stress in the upper and lower shaft of the punch?L length of the adjustable wrench in the figure; Choose a number from 152 to 252 mm that does not end with a zero. F force also; Choose from 122 to 292 N as a non-zero number. Find the torque and direction of the wrench applied to the bolt. ?the QUESTION 2: (30 points) For the shaft in below, motor gives a 500 Nm torque on the shaft when it is rotation with a constant speed. Torques of two pulleys are known as shown in the figure. If the shaft is made of A-36 steel alloy, determine the maximum shear stress that is generated through the shaft. 300 N - m 200 N m 48 mm 0.9 m 44 mm 1.2 m 40 mm 1m
- Q-3 A 25-mm-diameter solid round bar has a groove 2.5-mm deep with a 2.5-mm radius machined into it. The bar is made of AISI 1050 CD steel and is subjected to a purely reversing torque of 250 N-m. For the S-N curve of this material, let f= 0.9.The figure below is a schematic drawing of a shaft that supports two V-belt pulleys. The loose belt tension on the pulley at A is 15% of the tension on the tight side. The shaft material has a yield strength of 300 MPa and an ultimate tensile strength of 520 MPa. Calculate the shaft diameter.L21. Figure P4-21 shows an anvil for an impact hammer held in a fixture by a circular pin. If the force is to be 500 lb, specify a suitable diameter for the steel pin if it is to be made from SAE 1040 WQT 900. 4-21
