A rod AD of length 40 cm is suspended from point D as shown in figure. If it has a weight of 25 N and also supports a load of 40N,find the tension in the cable using the method of virtual work.Take AC=30 cm.
Given : Length of rod AD=40cm=0.4m
Load on rod AD=40N
To find : Tension in the cable
Block A of weight 2000N is kept on the inclined plane at 35° .It is connected to weight B by an inextensible string passing over smooth pulley.
Determine the weight of pan B so that B just moves down.Assume μ=0.2.
Given : Weight of block A=2000N
Angle of inclined plane = 35°
To find : Weight of pan B
Three blocks A,B and C of masses 3 kg,2 kg and 7 kg respectively are connected as shown.Determine the acceleration of A,B and C.Also find the tension in the string.
Given : mA=3kg
To find: Acceleration of blocks A,B and C
