A steel wire can withstand a load up to 2940 N. A load of 150 kg is suspended from a rigid support . The maximum angle through which the wire can be displaced from the mean position , so that the wire does not break when the load passes through the position of equilibrium , is

A

`30^@`

B

`60^@`

C

`80^@`

D

`85^@`

Text Solution

Verified by Experts

The correct Answer is:
B
At equilibrium
`Tcostheta=mg`
`sos theta=(mg)/T = (150xx9.8)/2940 =1/2`
`therefore theta=60^@`

A load of 1 kg weight is a attached to one end of a steel wire of area of cros-section 3 mm^(2) and Young's modulus 10^11 Nm^-2 . The other end is suspended vertically from a hook on a wall, then the load is pulled horizontally and released. When the load passes through its lowest position the fractional change in length is (10ms^-2)

An aluminium wire and a steel wire of the same length and cross-section are joined end to end. The composite wire is hund from a rigid support and a load is suspended from the free end. If the increase in the length of the composite wire is 2.7mm, find the increase in the length of each wire. (Y_(Al)=0.7xx10^(11)Nm^(-2), Y_("steel")=2xx10^(11)Nm^(-2))

A wire can support a load Mg without breaking. It is cut into two equal parts. The maximum load that each part can support is

A wire can be broken by 400 kg.wt. The load required to break the wire of double the thickness of the same material will be
