1. A gyroscope consists of a rotating disk with a 25 cm radius suitably mounted at the midpoint of a 20 cm long axle so that it can spin and precess freely. One end is supported by a stand. The disk spins at 2000 rpm. The mass of the disk is 2 kg, and the axle can be taken as massless. a. Draw the gyroscope, indicating the direction of the initial angular speed and the initial angular momentum. Choose a...

Question 10 (1 point) A piece of stainless steel (specific heat -0.50 Jg-loc-1) is transferred from an oven at (1.789x10^2) °C into 150. ml of water at (2.4x10^1) °C. The water temperature rises to 31.5 °C. Assuming that there is no heat loss and no loss of water vapour, calculate the mass (in g) of the piece of steel. Use data from the textbook. Pay attention to significant figures, keeping in mind that a temperature difference is measured in the...

The dimensions of the planar mechanism, shown in Fig. 1 are
given in Table 1. Link 1 is rotating at
constant 120 rpm in counterclockwise direction. The external
force of 200N is applied on the slider
at point D against its translational motion. Assume the link
bars of the mechanism are homogeneous
rectangular prisms with the width of 0.01 m and the depth of
0.001 m. The slider has the width of
0.070 m, the height of 0.040 m, and...

A gear reduction unit uses the countershaft shown in the figure. The solid steel shaft is simply supported by bearings at points O and C. Gear A receives power from another gear with the transmitted force FA applied at the 200 pressure angle as shown. The power is transmitted through the shaft and delivered through gear B through a transmitted force Fa at the pressure angle shown. 0 350 mm 225 ma Gear A 500-mm dia Gear B 200 mm...

Figure 1 shows the layout of countershaft used to transmit power to a blower through a pulley drive (4-5). Pulley (driving sheave) 4 has a diameter of 125-mm and pulley (driven sheave) 5 has a diameter of 75 mm. Pulley 5 is mounted vertically below pulley 4 (as shown in the figure). Belt tension on the loose side is 20% of the tension on the tight side. A power of 7.5 kW is transmitted via the gear set (2-3) from...
